Changing the HDMI output mode on 5D3 to 1080p50 or 60 possible?

[rlajos]

I want to use the 5D3 with an ATEM PS 4K video switcher with mode 1080p50. Can somebody help me is there a way to adjust the HDMI output resolution/mode with ML?
(Normally the HDMI output has 50i and 24p modes in PAL setting...)

Thanks,
