Switch over to external crystal without softdevice?

nRF52832

There are three ways of working with the clock registers, a hardware access layer macro set, the nrf_drv_clock.c/h, and direct register access.

What is the recommended way to switch from 64Mhz CPU on internal osc to 64Mhz high precision external?

There seem to be some ways to do it in drv_clock but it calls for an argument that is a clock strict instance I can’t find documentation for.

I’ve seen it written that clock confit is done only at start but that seems likes it only applies to softdevice projects.

Is there an way to switch between low precision and high hfclk ?
