I'm unsure if my new TV does 4:4:4 on 24Hz as well, they only stated that it does 8bit 4:4:4 at 50/60Hz with PC mode on and UHD color on.

Should i thus decrease native bitdepth to -> 8bit, and disable DX11 10bit?

The Blurays i have are encoded in 4:2:0 and probably 8bit color, if i understood correctly, MadVR will upscale it to 4:4:4 RGB & 10bit?

4:4:4 is a description of chroma subsampling using the Y'CbCr color space. madVR will output as RGB, which is 4:4:4 (or equivalent). Some TVs will want to convert the RGB output back to Y'CbCr. This could mean down-converting to 4:2:2 or 4:4:4. This would remain true regardless of the bit depth (8 or 10-bit).

In either case, this should not make much of a difference. There is a 4:4:4 test image in the Image Scaling section of the set-up guide if you are curious what your TV does to the signal. But 10-bit RGB is, of course, possible with any TV.

4:2:0 = 8 Bits
4:2:2 = 10 Bits
4:4:4 = 12 Bits?

RGB is measured in bits per channel: 8-bits per channel or 10-bits per channel.

So, RGB 4:4:4 at 10 bits would be equal to 30 bits. RGB 4:2:2 would be 20 bits.

So MadVR actually does output in HDR format without the dolby program?

What happens if the TV doesn't support 4:4:4, will the TV or the GPU be left to downgrade it to 4:2:2 or will MadVR detect it (If Nvidia control panel is set to RGB). Cause RGB is dynamic from what i understood? It doesn't need switching from 444 to 422 etc in control panel?

You should output RGB at the graphics card (where 4:4:4 does not exist). Let the TV convert to Y'CbCr if need be. It is difficult to determine what the TV is doing sometimes, so it is best not assume what the TV wants.
