LCR 4 ohm speakers. Atmos and Surround are 8 ohm. What should I set my receiver at?

Onkyo TX RZ50. Front 3 Monoprice speakers are 4ohm speakers. Atmos and surround speakers are 8ohm speakers.

Should I just set all my speakers to 8ohm and be done with it or set the 3 LCR to 4 ohm?
Thx

Leave at the higher setting, and it's not particularly about your speakers having different nominal impedance ratings. Here's the Audioholics article on the subject https://www.audioholics.com/audio-amplifier/impedance-selector-switch-1
