Any Ryzen mobo's that let you turn of hyperthreading?

Why do you hate it?
The Asus X370 pro allows disabling now, but I don't think I would recommend it.
It's not 2002 - it generally works fine - not sure what issue you have with it?
Well, my main issue with is i like to monitor cpu usage and hyperthreading makes cpu be misleading as it reports 1 real core as 2 so the percentage cpu usage displayed is always wrong and it just bugs me. yeah i know its a bit ocd but it just bugs the hell out of me so if i can turn it off, i will.
It's not misleading or wrong though? In terms of actual CPU usage, by disabling HT you are actually limiting the CPU's maximum usage (i.e. leaving execution units empty that could otherwise be doing useful work). Unless it causes a genuine performance regression (e.g. in some of the games identified in ryzen reviews) then leave it on as opposed to throwing away performance that is actually useable in most tasks.
CPU performance is rarely represented well anyhow - it could be showing 100% utilisation but much of the CPU is underworked or low utilisation but the CPU is wasting cycles, etc. etc. could switch over to the graph that shows overall utilisation rather than per core if you want something that is roughly representative but still very wrong of how the whole CPU is working.

Gigabyte B350 boards allow you to disable SMT also in the CPU features section.
That's a specific use case though - not just because "the usage looks wrong"
Mark2410 wants to turn it off. I can understand why he wants to turn them off. However the reality is a far more complex than this. As we know microsoft and AMD are working to sort out the windows kernel to make full use of Ryzens architecture so turning it off will have performance degradation. It took intel and microsoft and developers years to sort out hyperthreading.
Each to their own, but seems bonkers to buy a high performing processor and then choose to turn off some of the performance - may as well buy a chip that doesn't feature HT/SMT instead.
Surely there must be a configurable CPU monitor program that you can get and just "hide" the logical cores, if seeing them bothers you so much?

I was a bit iffy with HT at first, with the P4 3.6 HT CPU, but to be worried or even want to do something as silly as turn it off, is really absolutely nonsensical.
HT gives a CPU about 30% increase in many things and so turning it off is simply ludicrous.
