Change JTAG Clock. USB-Blaster

Is there a possible to change the JTAG Clock TCK over Quartus? We program over JTAG and have in a chain a delay around a BIT. The problem could be solved with a slower CLOCK of the JTAG.

There's a 24 MHz clock oscillator inside the USB Blaster (3.3V, 5x7 mm SMD standard package, next to the CPLD). I assume, that replacing it with a lower frequency would help for the said problem. I didn't try the solution.
