Is it possible to deploy FR1 and FR2 on same gNB?

Network always run on feature.

LTE NR Working.

CA between LTE and NR in ENDC I think not work individually. We can use for both legs CA.

Possible if: control board support, 2 baseband board support, 2 rru support.

Thanks! So ENDC can be done with both from LTE end.

Yes.
mmWave now I know only in NSA.
