Hibernation vs Secure Boot

[Patrick O'Callaghan]

I keep getting this in the journal:

Lockdown: systemd-logind: hibernation is restricted; see man kernel_lockdown.7

and a glance at the man page reveals that hibernation and secure boot
don't play nice unless the swap image filesystem is encrypted. My
immediate reaction is to disable Secure Boot, but I'd like to know if
there's an easy workaround, bearing in mind that my system is set to
hibernate overnight and wake up automatically in the morning, without
me having to type in a password.
