With Office 365 you could do:

=LET( GUID, C3,
            tmpGUID, REDUCE(GUID,{"{","-","}"},LAMBDA(t,o,SUBSTITUTE(t,o,""))),
            octetStr, MID(tmpGUID, 7, 2) & MID(tmpGUID, 5, 2) & MID(tmpGUID, 3, 2) & MID(tmpGUID, 1, 2) & MID(tmpGUID, 11, 2) & MID(tmpGUID, 9, 2) & MID(tmpGUID, 15, 2) & MID(tmpGUID, 13, 2) & MID(tmpGUID, 17, LEN(tmpGUID)),
            LOWER(octetStr) )

Where C3 is the target GUID.
