As long as you follow the GPIO usage restrictions, there's no problem to route it like you do. But you seem to have an extra component in the matching netwotk, the nRF52832 matching network normally looks like this:

Thanks a lot Turbo. Yup, should have read the datasheet thoroughly. Also just found out that low drive is defined as < 0.5mA.

If you read the PS, there is chapter 4.3: "GPIO usage restrictions".

There are mutiple pins restricted to low drive and low frequency (<10kHz).
