Linux has support for dm-verity that can be used to provide strong secure boot protection, by verifying every disk read. But for it to work, the partition holding the operating system must be read-only and updated in a similar manner to GrapheneOS where a new signed OS image is downloaded and written. Desktop Linux update model of updating individual packages are not compatible with that. So it is not so likely mainstream desktop Linux will get these features anytime soon. Tails could theoretically switch to use dm-verity, since they already have the right update model and are highly interested in security, but they haven't as far as I know. Also, the security BIOS offers to not be able to circumvent secure boot is sketchy at best.
But I often feel the security benefits of secure boot/verified boot is often overstated. It is only secure until user installed applications start executing. If a user installed application were able to compromise the OS once, they can redo it at every reboot, and most OSes auto-start user installed applications. This has probably also been a contributing factor to the low interest in secure boot on desktop Linux. QubesOS thinks it is far more important to harden dom0 against being able to be compromised at all in the first place. A secure boot/verified boot really only provide the following security benefits:
1) Secure factory default, ie a way to trigger factory default before any user writable/non-verified partition has been mounted. This allow to restore a compromised system to a non-compromised state, without reinstalling the OS from verified external media. But you will either way lose all your data. This is mostly a convenience function to make it easier to restore security post-compromise.
2) Evil maid protection, ie a way to prevent someone with physical access to your device, but without your login credentials, from modifying or compromising the system. For this to work, all user writable/non-verifiable partitions must be encrypted with your login credentials. But it isn't that hard for an evil maid to get hold of your login credentials, with hardware key loggers or carefully placed pinhole cameras, it just raises the bar somewhat.
