Boot Loader Specification support? · Issue #37 · Tow-Boot

Not yet. But maybe it shouldn't. Instead it would be better advised to run systemd-boot IMO. I disagree.

Ubuntu Manpage: bootctl - Control EFI firmware boot

Similarly, Boot Loader Specification Type #2 entries should be placed in the directory "$(bootctl -x)/EFI/Linux/". Note that this option (similar to the --print-booth-path option mentioned above), is available independently from the boot loader used, i.e. also without systemd-boot being installed.

Note: if your system hangs randomly when booted, you can try adding intel_idle.max_cstate=1 to kernel parameters before booting (press e when you see systemd-boot prompt to enter editing mode).
