Hi,
I'm not entirely sure what you mean by "uncheck activation functions", but I'm assuming you want to remove these fields from the product addition/edition pages for vendors.
You should use the ACL system to do so: In the HikaShop/HikaMarket backend, go to -> HikaMarket -> Configuration -> Main tab -> Access level. In the 'tree' there, unfold "product", then "edit". Here you uncheck (indeed!) what you don't want the vendor to see, then save and reload the product addition/edition page in the frontend.
