By blocking KVM. Enable or fake hyper-v? Block various qemu drivers. Don't use any of the qemu drivers? Side channels to detect KVM. Stronger hyper-v purity integrity. Detect nested hypervisors, which will have poor performance anyway. If you arent virtualizing disk drives and get banned. They will get serial banned, along with your other non virtualized hardware. GPU, monitors, ram, motherboard, keyboard, mice, headset serials. Yes, these are really all collected. No myth. Some people think server side anticheat can help. It can to a degree. Then some things will always be possible client side. Game devs need more subtle client side integrity checks inside the game, not only ones that purely check the integrity of your overall system. It's a losing battle, especially on games using the most popular engines like unreal and unity.
