I have checked this forum and other locations and not found any information concerning this problem on a Cmod S7.
To maintain synchronization in my system I would like to substitute the on board 12MHz with a 25 MHz clock. The on board clock is feed to the FPGA though pin M9 (an MRCC input on bank 14). I was planning to feed the new 25 MHz clock through Pmod pin J7 (also a MRCC input on bank 34). I was not planning to disconnect after connecting the new clock. After connecting the new clock I believe that I must make some changes to the Constraint File so the board recognizes and uses the 25 MHz clock.
