Yes, you definitely can.
Use Raspberry Pi Imager to write Recalbox directly to ssd.
Then use an sd card to write the bios options to boot from usb ssd (from the same raspberry pi imager, choose misc utility images -> bootloader -> usb boot)
Boot the Raspberry pi from sd card once until the screen goes green.
Then insert ssd and boot recalbox from it.
Good luck!
