Welcome to the forums @nofear.

I am not aware of any way to add option 90 to the stock firmware. However, if you are open to installing Merlin's custom software on your router, then adding option 90 via /jffs/configs/dnsmasq.conf.add script is very easy.

Edit: Forgot to mention, the other thing to consider is if either the stock version or Merlin version of dnsmasq supports option 90 (authentication). Just because it is in the white paper does not mean the specific implementation supports it.

The option would have to be added to the udhcpc command line rather than dnsmasq.

My mistake, thanks Colin.

I found this request for the same in 2018 and RMerlin said he wouldn't implement it:

It's not a tutorial. The udhcpc command is hard coded into the firmware. It can't be changed with a script. You would need to compile your own custom version of the firmware.

As far as I can see, there is not a config script in Merlin for udhcpc (https://github.com/RMerl/asuswrt-merlin.ng/wiki/Custom-config-files), so it looks like even using Merlin's software is not going to help.

Sorry
