Not currently. BUT..
There is a CLOSED source Linux flatpak that does appear to work pretty well on Linux. So in theory it could work on BSD but the app is using the android roblox binary via both wine and an android emulator.
See their website : https://sober.vinegarhq.org
And their github is for only reporting issues:
vinegarhq/soberissues
You could ask on their Discord server or open a github issue and ask about FreeBSD/GhostBSD package ?
