do i have to have wifi with esp-now

[sajjadakhter]

hi, examples i see uses wifi to discover master/salve. Once I have discovered master and salve and save it to flash (spf) etc
Can I turnoff wifi if I don't need it as I only need to use esp-now.
considering esp-now using some part of wifi can I turn off some parts off that help me save power and may help achieve longer range.

Thanks
