How use-friendly is the RBR config (inc DHCP)?

This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktop

As background, primarily I want to assign fixed IPs to at least some stuff in the house; currently we have a Virgin “Super”Hub 3, which is anything but in this regard. It dangles the promise of the functionality before you, but every single addition or edit takes about a minute to commit and generally causes everything else connected to the SH3 to get disconnected, at least temporarily. It really is a bag of spanners.
So, just some reassurance that I can easily (with the Orbi) define an internal IP range and add reserved addresses in seconds, rather than frustrating minutes, would be appreciated!
Also... is it possible to “fix” a particular device to use only 2.4GHz or only 5GHz, rather than having the Orbi switch between the two?
The SH3 again offers this but it’s a right PITA to actually set up, and without it my laptop can be happily getting 100Mbps in the 5GHz channel and then get shuffled onto the 2.4GHz where, thanks to probably various factors of location and contention, it struggles to get 2Mbps.
Many thanks in advance!
