In light of the CrowdStrike-Microsoft outage/disaster that has been wreaking havoc on corporate Windows systems around the world since Friday, systemd lead developer Lennart Poettering pointed out how such a situation on Linux systems could be averted by leveraging systemd's Automatic Boot Assessment functionality.

System's Automatic Boot Assessment feature can allow for reverting to a previous version of the OS or kernel automatically when a system consistently fails to boot. With the systemd-boot bootloader and related tooling within systemd and leveraging the Boot Loader Specification, systemd Automatic Boot Assessment would make for much easier recovery in case of an incident like what happened with Microsoft Windows systems running CrowdStrike software last week.

Well at that point, just don't install any kernel mode EDR software at all.

NixOS can be set up for impermanence where all config is recreated every boot and nothing persists besides the nix store. There's helpers for ephemeral home also, so you can have something like TailsOS. I'm sure you could do that with other distros but you'd need absolute discipline to have everything the machine needs provisioned at boot.
