AX5200 - RAX48 model WiFi 6 first generation device.
advance- lan setup, add ip address / mac address and device name. I have 70 devices 36 are smart devices ( Blubs, switches, camers......). Router will NOT put all devices to lan setup ip address. Mac address correct, reboot, reload cfg, reset... Nothing works. Call support pass 90 day so here I am asking for help.
"will NOT" is not a useful problem description. It does not say what you did. It does not say what happened when you did it. As usual, showing actual actions (commands) with their actual results (error messages, LED indicators, ...) can be more helpful than vague descriptions or interpretations.
What happens when you try?

See "not a useful problem description [...]", above.

That may be too many. Besides any limit on address reservations, I seem to recall seeing a limit of 32 devices per radio. If all your Internet-of-Junk ("smart") devices use 2.4GHz, then having 36 of them might be another source of trouble.
Adding a wireless access point could reduce the number of devices per radio. If the DHCP server in the router simply can't/won't handle that many address reservations, then you'd need to use a separate device as a DHCP server. Raspberry Pi?
Why do you need to reserve an address for every device?
