Remapping/rotating Switch Joy Stick possible?

[cubes]

Probably a weird request.

MelonDS has the option to play games sideways.

I would like to use the joy stick while playing sideways.

Is it possible to remap/rotate the joy stick 90° using homebrew?

It looks as if Nintendo already has a feature for that :

They do but it can't rotate the joy stick
