Can Exchange Rate Variances (ERV) be Stopped from Interfacing to fixed assets

We have modified the Accounting Class Assignments for Mass Additions to not let ERV (Exchange Rate Variance) go through. Even after ERV being turned off the assets are still being revalued based on the exchange rate i.e if the invoice created in AP is having ERV ,then ERV is getting interfaced to Fixed assets and getting tied to the corresponding assets.

We do not want ERV to interface to FA.

We checked the code for the IPV process and see that the below elements are hardcoded to be interfaced to Fixed assets regardless of what we set up in the accounting options set up in PAYABLES-
