I asked about it in #825071821594034196, but this channel seems more fitting:
Can we add an option to enable/disable specific external clients via API calls?
Currently, the only way to disable a client (even temporarily, as far as I'm aware) is to delete it entirely, but then we must re-create a similar in order to 'enable' it again, but that means the keys get regenerated and we must reconfigure the client accordingly
