No, this is intentionally restricted.
Using noise reduction on a data signal can introduce distortion to the
signal. The demodulator,if properly designed, will be matched to the
expected signal
...I believe the device listed as U29 on the K3 schematic may be a

The schematic is correct, U29 is a TLV320DAC23.

I think your suggestion would work if I tied the two PTT ouputs (one from K3

Another option would be to have a second set of paddles connected to the K3,
for barefoot operation of the K3.
