Disabling RTCK

When programming via JTAG, how do you disable RTCK in MCUxpresso? Page 85 of MCUxpresso IDE User Guide indicates it is possible to disable RTCK.

1. Which chip are you using?

2. Why do you want to change?

Note the comment:

Note that RTCK (Return clock) is only used on older ARM cores (ARM7TDMI and ARM9 family) before the debug was properly decoupled from the core clock domain.

I am using a MIMXRT 1020 board I was confused on why connecting RTCK and not TCK with a minimum pin configuration allowed the JTAG connection to work. I was wondering if it was because RTCK was enabled. Thank you!
