Disable LTE band 20 800mhz

[qbert]

My carrier has some weird issues with its 4g, band 20 LTE gives awful speeds compared to 3g. I use the Three network, UK.

So I'd actually like to know if I can disable band 20 for 4g so the other bands will still work.

I can set 3g only using settings but it's only band 20 that I need to avoid!

Anyone know if it's possible to turn off band 20 only please?

Here's my speed results, speaks for itself, the 4g is using band 20 other 4g bands seem OK but can't show that right now as band 20 is being preferred.
