If you do a DUMP ALL in CLI the first few lines identify the existing firmware version and that includes the board ID
For example…
dump all
version
INAV/MATEKF722SE 2.5.0 May 26 2020 / 12:36:10 (d84bcb733)
GCC-9.2.1 20191025 (release) [ARM/arm-9-branch revision 277599]

From the cli if you type version you will see what the target is.
