At approximately 200 ft. AGL on an autopilot off approach to DFW; we received multiple alerts most of which were too brief to decipher. One that we did catch was 'use manual spoilers'. Since auto spoilers rely on the radio altimeters we suspected 5G interference. The alerts were brief and all systems appeared to work normally during the landing. We were not able to analyze this until after the flight; therefore; Tower was not notified.
Air Carrier Pilot reported receiving multiple alert messages on final approach at DFW and suspected possible 5G interference.
