Disabling Certain Default Rest Endpoints

Hi. is there a way so specifically disable rest endpoints when a user is not logged in?

I use the API, but I have reason to want certain endpoints to be disabled for certain cases.

I’ve got an is_rest() function. But was only able to make it determine if this is a REST API request and not if it is a specific REST API request.

I’d appreciate any info. Thanks.

(PLEASE DON’T COMMENT ON WHY NOT TO DO THIS.)
