Is there a way to get into the bios logs and see when a bios password was added?
That would depend on whose BIOS it is. Contact the motherboard manufacturer, give them the motherboard model number, and ask them.
If it helps, I can tell you that the BIOS on Intel's Desktop Board, NUC and Compute Stick products do not place entries in the BIOS event log that indicate when a password was added.
