I checked the developers website, there is not a natif Linux version.
I tried to setup a virtual machine but I didn't succeded.
Wine or Bottle was not a solution at all since it kept crashing.
I tried with a Windows-To-Go drive it was working well, but the installation, config and updates and usability are really slow plus the drive was getting really hot.
I went back to a dual-boot Windows 11/ZorinOS and for me it's the best solution, because I can use the trackpad gesture in the software. That wasn't the case in Wine/Bottles.
Windows won't be connected online since I just use it for the softwares.
Plus I also needed Affinity Designer that can't be emulated with Wine/Bottles.
TL;DR: So for me FL Studio cannot be used on Linux with Wine/Bottles right now and went back to dual-boot: Windows 11/ZorinOS.
