There are unofficial versions (such as Flatpak) but I don't think that any of them will overcome the fact that the Raspberry Pi Foundation has built their Debian Desktop OS as 32-bit and Joplin requires 64-bit.
The issue of 32-bit has arisen before and does not appear to have been resolved by anyone who wants to run Joplin on a 32-bit OS.
Assuming you want to keep with this OS a check of the RasPi downloads server shows only rpd_x86 so a 64-bit Raspberry Pi Desktop for PC does not appear to be an option either.
The Joplin AppImage works fine on Linux Mint
