As the tittle, how can I select frequency for radio frequency. I use nrf52 MCU.

Jesus NO! BLE has defined behavior on radio channels on PHY and LL layers. This is managed by stack (e.g. Nordic Soft Device if you use that). In advertising/broadcasting stage you can only say which from ADV channels you want to use or not. During connection all remaining channels are used according to hopping sequence set by Master/Central during CONNECT_REQ. Seriously read some more sources about BLE if you want to use it.
