Hello Meot, Louis,
Thank you for posting in Q&A forum.
Is there any issue with removing this default permission and putting directly my Service accounts identities?
A: I think you can remove this default permission and add your service accounts.
However, you should also change service account from default permission to your service account on specific service on that server.
