Path tracing render with ACEScg color profile create noise on the highlights

I’m trying to render a shot using path tracer in Unreal Engine 5.1, as soon as I enable ACEScg color space I notices that some of the bokeh gets visibly noisy, I lowered the “max path exposure” in the volume to avoid fireflies in the render but the problem persist, also I noticed that all the areas where the roughness of the material is more prominent texts to get noisy even if I crank the antialiasing samples in the movie render queue. Any idea what could cause the problem?

I attached a couple of stills to highlight the problem

Same issue here, I can use da vinci to get rid of those with the temporal denoiser but it’s kind of an annoying problem I haven’t been able to solve yet
