You can find the procedures for removing and reinstalling, the Mini Tower version's coin-cell battery, on pages 33/34 here:

There is no 'Button' installed on the motherboard to reset the BIOS/CMOS to defaults.
To reset the BIOS/CMOS, remove the coin-cell battery located on the motherboard, wait 5 minutes, then reinstall the battery
The procedures for this are listed in the OptiPlex 790 Owners Manual.
Which version of the OptiPlex 790, do you have, the Mini Tower, Desktop, Small Form Factor, or the Ultra Small Form Factor?
