The community version is free (with some restrictions) and is available on windows and linux, so you simply need to create an account on NI's website and download it, activation is needed but should work anyway.
There is a project that might be a nice starting point for you if you want it in Linux : the LabVIEW Community Training, it's at an early stage but it provides an OpenSuse VM with LabVIEW Community installed, you can get it from GCentral : https://downloads.gcentral.org/vm/20231021_OpenSUSE_CTIBase.ova
Hope this helps
