No, as far as I know. I haven't used Debian-based distros in years, so I'm unsure of the situation there, to be fair. There are other approaches, e.g. Guix and NixOS as mentioned by others, but you also can get most of Silverblue's benefits from BTRFS/ZFS and a package manager that can create snapshots. Not sure if apt integrates like that. For me, Silverblue just enforces good defaults: the base OS is as simple as needed and I only install necessary applications through Flatpak, which has some security benefits over direct package installations. VMs are for more involved work with potentially risky software (i.e. development environments with random NPM dependencies).
