SD Card uSDHC CD_B Pin Problem

On our custom board (imx6q) we skipped the fact that when not used CD_B pin should be grounded. We have no means to alter this pin physically. On this port we have SD Card connector witch CMD, CLK and D[0..3]. 


Now, I wish to ask, am I doomed? Can I still somehow force controller belive that there is a card inserted even though we left the designated pin (CD_B) floating?


I greatly appreciate any help on this subject since this is very critical for booting of our custom board. Please someone come up with a solution.


Thanks in advance,
