Hide Fields from Entity Views based on the Record Owner and manager

Hi,

I wanted to hide/Non-Readable the few fields from the Entity Views if the CRM Logged-In user is not a record's owner or manager of that Owner.

Here, I am able to hide/Non-Readable few fields when user opens the records using Scripts but I am not able make it hide/non-readable to fields from Entity Views?

So, please let me know if any one achieved this kind of requirement.

FYI, I can't use field level security since I wanted to hide/non-readable the fields based on the record's owner/manager.

Thanks in Advance.
