Same thing for any other software, see if you can get it running in wine, and see what the alternatives are and try them out until you find a solution you like. You need to accept there may be change, and may need to experiment and hit up Google to find solutions, but solutions do exist.
From a quick Google search, i found about 4/5 potential open source options
FreeCAD would probably be what I try first, but it's hardly the only option and seen some people complain that it feels archaic (but it's FOSS). I've also seen draftsight recommended a few times, and it has a free trial but is not free.
Also apparently fusion360 has a web interface that may be usable.
I've heard of people getting fusion 360 running great with a snap, but others say it has issues. the github for it is being actively maintained, so thats a good sign at least.
I tried to get siemens solid edge working through wine, but it was mostly broken and I didn't dig too deep into troubleshooting, I just dualboot windows for fussy programs and anticheats
