Prior to amendment effective from 01.01.2022, Section 151 reads as follows:
"Power to collect statistics.
151. (1) The Commissioner may, if he considers that it is necessary so to do, by notification, direct that statistics may be collected relating to any matter dealt with by or in connection with this Act.
(2) Upon such notification being issued, the Commissioner, or any person authorised by him in this behalf, may call upon the concerned persons to furnish such information or returns, in such form and manner as may be prescribed, relating to any matter in respect of which statistics is to be collected."
So, said section 151 was mainly dealing with power to collect 'statistics'. Hence, said section does not give powers to Commissioner (in my view) to order 'information' u/s 151 for purpose of carrying any investigation against any registered taxable person about wrong / irregular availment of ITC. Such powers are indeed available to Dept. / Commissioner but under other provisions (such as Section 67 to 72 of the CGST Act, 2017)
From your query, it appears to me that issue is gone much beyond of powers of Commissioner u/s 151 and accuracy of his order so issued u/s 151.
If I understood correctly from your query, you are not interested challenging such order u/s 151 as such. but, your main issue & concern is resultant order in Form DRC-07 and subsequent back attachment.
Now, it is fact that you already got notice in Form DRC-01 & then order in DRC - 07. And basic legal recourse is to challenge the order before appellate authority giving your grounds of defense.
If ONLY basis for confirming demand in DRC-07 (i.e. for alleged wrong availment of ITC) is non-submission of asked information to Commissioner against order u/s 151 (1)and absolutely nothing more and then, you can approach High court by filing the writ petition in my view (by arguing that commissioner lacked powers to order sought 'information' u/s 151)
Approaching directly High court is also applicable if no personal hearing is granted before passing the subject.
Please remember that approaching HC - through writ petitions - can be costly affair with no certainty of closure of the issue - once for all. You may loose time-limit to file appeal with appellate authority - in between - which can create another sets of legal challenges if HC does not give you sought relief / closure.
In the context under discussion and considering the fact that we are not aware of actual contents of order u/s 151 (1), notice in DRC-01 & order in DRC-07, you need to also consider section 155 of the CGST Act, 2017 (i.e. Where any person claims that he is eligible for input tax credit under this Act, the burden of proving such claim shall lie on such person.) before choosing a particular course of action.
Another set of legal issue to be considered - beforehand - is amended Section 151 (effective from 01.01.2022) & potential effects of those amendment (if any) in your situation, if said order is issued by commissioner on or after 01.01.2022. (I have not given any thought on this aspect yet, in the context of your situation).
Hence, in summary, you need to take a comprehensive call whether you want to approach High court or file appeal with first appellate authority after taking various legal provisions, 'facts' as may be applicable in your situation, costs and risks involved in each of two options.
These are ex facie views of mine and the same should not be construed as professional advice / suggestion.
