OpenWrt
No support found. Checked against OpenWrt's own Table of Hardware, which carries no qualifying row for this model. That is a weaker statement than "this router cannot run OpenWrt" and a much stronger one than silence.
No ToH row for any current Netgear entry. The Netgear models OpenWrt does cover, such as the R7800, are older and none of them are in this lineup.

- OFDMA
What is OFDMA?
Table stakes50 of 79 listed here
Splits a channel into smaller slices so several devices are served in the same instant instead of taking turns.
Look at instead: streams per radio and channel width — those set the ceiling OFDMA divides up

What is Band steering?
Depends on your setup16 of 79 listed here
Nudges a device onto the faster band when it would otherwise settle on the slow one and stay there.
Look at instead: whether the router lets you split the bands into separate networks — some devices need that
