If youre talking about the rear, you cant without having a hub where you can swap out the end caps

Thanks, it is for front hub. Rear already have quick release. I need 20mm not 12mm.

From my understanding a 20mm thru axle is based on a longer axle standard (longer than 100mm) so the answer is entirely hub dependent and is based on whether your hub manufacturer has an adapter available

Yes, I believe that standard was short-lived and was 20x110, but was not Boost (rotor in same place as 15/12x100).

I have SRAM 900 front hubs that convert to the following with only tool-free end caps:

9x100 QR
12x100
15x100
20x110

In short, we need more info. What hub are you trying to convert, OP?

I found one made in Poland,,it is 20mmx100 mm but it moved a little.
