Is it possible for a client mod to have an effect on a server mod?

[. . .]

Hi, I have a mod which which uses a component when you press a button an action is preformed which a lot of mods have, the popular keyhandler component.

Now I was wondering if it would be possible in any way to give every player the ability to configure what button they want their action to be set to?

In server mods unfortunately even if I do add a configuration option to change the key to something else this would effect all players instead of an individual one which isn't really great, especially when some keyboards may be missing a few keys..

If anyone can tell me if this is feasible via some type of coding magic or it's impossible due to dst's limitations that would be really helpful! Thanks for taking the time to read my question !
