Hi @hari35 

There is no option to ‘restrict’ access to a ‘Vendor class’ or to ‘Deactivate’ a vendor class, so that its not available for selection while creating new vendors. 

Here is what you can do as workaround,

• create a dummy branch under one of your company
• restrict visibility of such vendor classes to above branch

This way, it should not be accessible when one tries create new vendor on any other Company/ branch (active ones).

I have not tested this, you may check at your end.
