Can I unlock my Samsung Tablet without Internet, or can I access internet while locked out?

I've locked myself out of my tablet. I haven't used it since high school, and forgot the password! It's a Samsung Tab E from 2015 I was able to find all the features for Find My Mobile, since I have a Samsung account registered with the Tablet, so I could hypothetically reset my password or get rid of the lock altogether - but, my tablet isn't connected to the internet, and I can't connect until I unlock my tablet :/ So, is there a way to connect to the internet without unlocking my tablet, or unlocking my tablet without the internet? I'm open to suggestions outside those offered in Find My Mobile
