Sharpening 4K + HDR Peak Brightness

Hi everyone. I've just got a new monitor which will finally let me watch HDR on my computer. I've not really used my copy of SVP much other than for youtube videos up to this point.

I'm after a little guidance on adding some sharpening to my 4K HDR films played via MPV. What i've read so far doesn't seem to work as its for the standard MVP not the one linked to SVP. Everything i've tried so far hasn't really worked. Any guidance really would be appreciated.

In addition is there anywhere I can set the peak brightness to 1000nits?

Monitor is an X35 3440x1440
2080ti, i7 8086k @ 5.2Ghz

Thanks in advance.
