Can SHSH blobs be extracted from Firmcache?

I'm newer to jailbreaking and a**le tech in general. I wasn't aware of how difficult it is to downgrade the iOS on my iPhone 8. When jailbreaking it, I upgraded to 14.4.1 and did not save my SHSH blobs. Now I'd like to downgrade to 13.5 and I don't have them.

I noticed that in my 3utools directory, there is a folder called Firmcache that looks like it has DMG image backups of the previous iOS versions of my phone.

My question is - is there a way to extract SHSH blobs from these files?
