While a "one-click software tool" does not exist, downgrading a PlayStation 4 is technically possible under very specific, highly complex conditions. It requires advanced hardware modification, soldering skills, and precise backups.
Many users seek to downgrade specific digital games to to exploit glitches for trophies or to regain original performance (e.g., The Last Guardian at 60fps). PS4 Firmware Downgrade: Reverting from 11.02 to 11.00

Modifying your console’s firmware carries inherent risks.
The PS4 must be completely taken apart to access the motherboard.
