Its found in the profile_header.tpl file in the jrNingja skin, so to alter it:
ACP -> SKINS -> NINGJA -> TEMPLATES -> profile_header.tpl -> MODIFY
The button code is on line 13 ish and looks like this:
{jrCore_module_function function="jrFollower_button" profile_id=$_profile_id title="Follow This Profile"}
So if you wrap that in a template block you can show it to just who you want to show it to.

I believe you have your community in its own separate quota, so maybe a quota block that checks which quota it is before showing the button.
In .tpl files you can add {debug} to figure out what variables are available on the page.
Docs: "{debug}"
https://www.jamroom.net/the-jamroom-network/documentation/jamroom-developers-guide/1477/debug
For you, you need to figure out which quota_id the 'community' profile is in and exclude all profiles with that quota_id from having the button.
(or you could use the specific profile_id if you JUST wanted that profile only)
Suggested code:
{if $profile_quota_id != 3}
{jrCore_module_function function="jrFollower_button" profile_id=$_profile_id title="Follow This Profile"}{/if}
which reads "If the profile quota id is not
3 then show the FOLLOW button.". But you will need to make sure that it is quota id 3 that is the one you want to exclude of course. If 'community' is in quota 2, then change the 3 to a 2.
