Q: Where am I supposed to see "[ 0.000000] ACPI: DSDT ACPI ..." #19

The README says:

If you see all three lines

[    0.000000] ACPI: DSDT ACPI table found in initrd [kernel/firmware/acpi/dsdt.aml][0x2338b]
[    0.000000] Lockdown: ACPI table override is restricted; see man kernel_lockdown.7
[    0.000000] ACPI: kernel is locked down, ignoring table override

rather than just the first line, disable Secure Boot

Where are we supposed to see that? During boot? I'm on Ubuntu 18.04.
