From FAQ:
What should I know about Linux support?
The new Epic Games Launcher runs natively on Linux, but many games are Windows-only builds and may need a compatibility layer. Check each game’s Linux compatibility before installing.
We support Ubuntu 22.04 LTS or newer, Fedora 43 or newer, and Debian 12 or newer. Other distributions may work but aren’t officially tested or supported.
Use the Send feedback button in the launcher to report issues.

Also epic is rebuilding Easy Anti-Cheat for Linux (EAC Linux v2) to deliver near-Windows-level protection using signed kernels, Secure Boot, TPM 2.0, and other existing Linux security features starting with a Fortnite, so more multiplayer games can finally support the platform without enabling widespread cheating.
A signed kernel does not directly mean that they will supply the kernel. They might work together with some distros and trust those signed kernels. Secure boot is often already used by Linux users. TPM I don't know.
