How can we add a restriction on the work confirmation page based on Inventory access

Hello Everyone,
Initially we had a requirement to restrict the GRN creation according to the project the receiver is assigned to, but we found that it was not possible. So we created different inventories for each project and gave the receiver inventory wise access. Now we are also creating complex orders and work confirmations. But we are not able to use that Inventory wise access for the work confirmation page.

Please suggest if anything can be done through VBS or any other method.
