Archer D is a router with DSL modem. OpenWRT doesn't support DSL modems.

That's why you can't find any information how to do it.

If I don't need to use DSL function, can I install OpenWrt. Or it's not supported at all.

This is official list:
https://openwrt.org/toh/views/toh_modem_supported

And Archer D wasn't there.

Archer D50 and D7 exists in the supported list. - https://openwrt.org/toh/start?dataflt[Model*~]=archer+d
If anyone has been successful on D20 or knows if it would work, would be helpful to know, as I was planning to give it a try.
Cheers & Thanks!
