Here is a small BASIC loader that can be used to perform a LOADM without the verify issue. It should work with any Disk Basic since the only ROM routine used is CONSOLE IN at $A176.
It utilizes a small machine code routine that it places in the first 50 bytes of the cassette buffer at $1DA (its position-independent so you can use a different address if needed). The routine does an auto EXEC after completing the LOADM, so there is no need to use a special segment in the bin file to do that.
Just change the file name in line 10 to LOADM the desired file.
30 READ B$:IF B$="XX" THEN 60
40 POKE A,VAL("&H"+B$)
50 A=A+1:GOTO 30
60 OPEN "I",1,FL$:POKE &H6F,1
70 EXEC &H1DA
