@1080P24 -> 4K

Maybe, if you lowered chroma upscaling to low and got rid of SuperRes. SuperRes doesn't work well with NGU, anyways.

@1080P60 -> 4K

Not a chance if you want to use NGU very high image upscaling.

@720P24 -> 4K

Seems likely if you stick to NGU high upscaling and lower chroma upscaling to low or medium.

@720P60 -> 4K

The same settings as above could work.

@480P24 -> 4K

It would work if you lowered chroma upscaling to medium or high.

@480P60 -> 4K

You might have to lower image upscaling to NGU high.
