Remove the "Post" button the Accounting Hub (AHCS) but no the General Ledger (GL)

Summary:

We need to remove the "Post" button from the "Create Subledger Journal" task in the Accounting Hub Cloud Service (AHCS) module without affecting the "Post" button from the "Create Journal" task in the General Ledger Cloud Service module ( GL). 

Is this achievable?

When I remove the "Post Journal" privilege from the custom role, the "Post" button in the AHCS and GL module is removed.
