That would be my guess - the only 2 Senators who voted against the new Defense Secretary Lloyd Austin were Hawley (MO) and Lee (Utah). There were also 5 who didn't vote (maybe some have "COVID" or were out of town?) - all 5 were "Republicans": Tillis (NC), Burr (NC), Capito (WV), Moran (KS), and Hyde-Smith (MS).
Here's where the Defense Secretary confirmation vote count per Senator is listed: https://www.senate.gov/legislative/LIS/roll_call_lists/roll_call_vote_cfm.cfm?congress=117&session=1&vote=00005
