How to disable upload in strapi for specific collection type and role?

I already setup RBAC for branch role they only can read the reward data:

Then I login using branch account, when I see reward detail. The Branch account can edit the image.

If I turn off the upload permissions for this roles they can’t update others CT. So, any suggestions to solve this?
