Lenovo Laptop BIOS recovery/flashback

Hello everyone! I recently bought a Lenovo Ideapad Flex 5 14ALC05. I had some issues with one of the charging ports and read a BIOS update fixed similar issues. I downloaded the BIOS update, but the program was rather unintuitive and I ended up bricking the laptop. It will accept power and charge, and even power on, but the screen doesn't turn on and as far as I'm aware no inputs do anything.

I naturally went to Lenovo's website and submitted a ticket and they sent me a shipping label to send it to their people. The problem is, estimated wait time is over a month and I'd like to explore any other viable option before committing to such a wait.

Is there anything I can do about this? Some way that I can recover or reinstall the BIOS without having to wait a month for someone else to do it?

Thank you all in advance!
