Target Display Mode iMac (2020) to PC

Hello everyone

Sorry for my English, it's half done through a translator.

My question is that I don't have 2 iMacs but I have a desktop PC and I would like to switch my iMac 2020 27*5K and use it as a monitor for a regular PC too. The output I saw lunadissplay for Mac to Mac but what about for Mac to PC? I spent money on thunderbolt 3, but then I saw on the forums that it does not work on 2019 and today's iMacs, but is there really no workaround or solution at all? I have a very powerful PC and I would be crazy to use the iMac 2020 27*5K as a monitor with the ability to switch as it was before cmd+F2, please tell me some way I'm sure there are people very advanced in this regard......
