PLO50 QQT9ss, quads too weak to raise river?

I'm an Omaha fish for high-only games, but I would think that a lot of full houses would bet that river.
Even so, I can see how royal flushes and quad Kings are distinct possibilities

But my question is Why not raise the turn?

I rarely have AA after just calling preflop and this is also likely reason MP decided to lead here. He has all AA after calling small flop stab. I want to keep his bluffs in like some Ax or AK type hand.

I guess I could have some miniscule raising range as AA is only third nuts in this case and perhaps mix in some form of Q+J♠: as very ballsy bluff. But even if we only raise turn as value with QQ or royal keeping villain range wider while in position is nice outcome from call. Plus recreational third player perhaps calls some nut flush if I just call.

If villain has AA or KK he will continue to value bet those on almost any river anyway and he might continue to rep those as bluffs. But if I raise turn those bluffs just snap fold most likely. My plan was to shove happily on river unless it's A or K. On A it's clear call only spot as KK is very unlikely to give action. On K I can see some value still in shove.

Anyway when I have QQ in my hand that leaves AK and AA only option as boats for villain to have.

I think there is too many (+FD) and combos in MP's range to not raise 4value in a vacuum. I think we have to discount to some degree, at least some of those should check-raise the flop 3way. For MP being the RFI are very well frequently within his range too, while bare also make sense to lead ott. J♠:T♠: being just a very few combos among plenty I would primarily be worried about :Kx:. Quads over quads is still a cooler pretty much always at 100bb. Kinda depends on how nitty villain is and if he has a block-betting range otr. Since this setup is so super rare, I personally would not worry about it (nor analyze it).
