How do I check the sha256 sum of my file’s certificate (not the sha256 sum of my file!)?

I am checking the integrity of the gpg4win installer on Windows and I would like to check the sha256 sum of my file’s certificate. My windows (Windows 11) only show the sha1 sum of my file’s certificate. How can I check sha256? Can I do this using SignTools or another tool provided by Microsoft? (I consider files from Microsoft servers to be more trusted.)

I tried to check via User Account Control->Show more details->Show information about the publisher’s certificate->Details-> Thumbprint There’s only sha1 there.

I’m looking for sha256 because the gpg4win website(https://wiki.gnupg.org/Gpg4win/CheckIntegrity) claims it’s better than sha1.
