                Lenovo T490, read password, or remove it

                Hi all.
                I have this lovely T490, where I would like to reinstall windows, but the Supervisor password is set, and for me unknown.
                I have read out the BIOS with CH341, and checked the MD5 sum for 2 files, at they are a match.

                Can I somehow decode the password, or can someone clean it for me?
                Hope somebody can help me out here :-)
