I think they’d be willing to help you with that stuff. I’ve had interactions that required doing something via command line and they were willing to help out and do it for me (because I’m still not super confident via command line).

Their pre-sales responses are pretty responsive so it might be best to ask with some examples of whether it’s in-scope or not.

Asking because I rarely need hosting-related support but when I do, it’s usually something fairly technical like a Let’s Encrypt renewal that failed for mysterious reasons or a PHP version update that failed to apply even though it’s a site that uses .htaccess and I’ve updated it with the proper .htaccess command.
