Update Secure Boot? (lemmy.ml)

GNOME Software tells me that there is a "Secure Boot dbx Configuration Update;" in the description below it reads:

"UEFI Secure Boot Forbidden Signature Database"

"This updates the list of forbidden signatures (the "dbx") to the latest release from Microsoft."

"An insecure version of Howyar's SysReturn software was added, due to a security vulnerability that allowed an attacker to bypass UEFI Secure Boot."

GNOME Firmware tells me that this update is not removeable or reversible, and I dimly remember there being something bad (perhaps incorrectly) about Secure Boot. So, what do you think, should I update it or ignore it?
