I want to format my PC Acer EX215-54-524A Windows 11 laptop PC to factory settings

Hi, I wanted to format my Acer EX215-54-524A Windows 11 laptop PC to factory settings, but I can't do it, because when I go to the settings and press reset the PC loads, I choose the settings (keep my files etc.. .) and once the PC is loaded it restarts and sends me to the UEFI settings, but then I don't know what to do because there is actually nothing that can make me continue the reformatting, so I press turn off the PC, but when I turn it back on it tells me that no changes were made, I also tried with the other setting (delete files, apps etc...) but it does the same thing again, how do I solve it?
