Better without local dimming bad for HDR?

I've been reading reviews, on mainly Rtings.com, and many budget gaming 27" monitor reviews, say "Terrible local dimming." and that it doesn't help in HDR, but that you also can't disable it.
It makes me think, that is it better then to get a monitor without local dimming? Does HDR look better on monitors without local dimming than those with it that still suck at it?
I know HDR400 isn't ideal for HDR but maybe still fun to try out at times

Thanks for the input! So in your opinion, HDR doesn't really matter on HDR400. But do you mean that to the extent that games look better in SDR on HDR400-only-monitors?
Since I'm not likely to buy a real HDR monitor, should I just not bother if the monitor has HDR then or not? Does full HDR gamut help at all in HDR400?

Another thing I was thinking about was Freesync premium pro. That enables VRR in HDR. Without it, Freesync doesn't work at all with HDR?
And related to that, looking at the Asus VG27AQ TUF. It says it has adaptive sync and that it is Gsync compatible, but doesn't mention Free Sync. Does that mean it won't it necessarily work with AMD GPU:s? I guess it should. But more importantly, it won't at least have LFC as I guess "adaptive sync" does not come with Freesync Premium features? I currenly have an old GPU so I will definitely run some games at 30-40 FPS
