If you do not know the device passcode, then no one can unlock your device, not even Samsung, not even Google. The device-level protection does not include backdoors to bypass the passcode as a security measure.
If you have access to your son's Samsung account, you can possibly use SmartThings Find to unlock the device remotely.
However in most cases, a factory reset is generally your only option to bypass the lock and make the phone usable again. Please be aware that this will erase all data from the device and will initialize the FRP lock.
FRP lock requires you to enter the previously associated Google account credentials. If you know your son's Gmail password, you will be able to access the device but unfortunately you will have lost any access to any data that hasn't been backed up.
