This machine >> MacBook Air (Retina, 13-inch, 2019) ?
First thing to do is, Always make a Time Machine Backup before proceeding
It maybe the Only way to protect your Personal Information and Data
Scorched Earth Method
This method will WIPE ALL Data and there is No DATA Recovery - Period.
To perform this action will require booting from a Bootable Installer.
The Bootable Installer can Only be performed on an Apple Computer
This will have to be performed from a Qualifying Computer to run the version of macOS to be made on the Bootable Installer.
Example : Bootable Installer of Big Sur would have to be done on a computer that Qualifies to run Big Sur.
Notation: If the computer being used to perform this action is Too New or Too Old to qualify to run the version of macOS - this computer can’t be used.
Alternative is, to gain access to a Qualifying Apple Computer from a family member, friend or associate.
Shutdown computer and disconnect all external drive Except the newly created Bootable Installer.
Restart and immediately hold the OPTION key until the Startup Manager appears and choose the USB Drive.
It will present options >> Disk Utilities >> View >> View ALL attached Drives.
Choose the Upper Most Drive ( not the volumes indented and list below ).
The drive normally is called Apple Media or Apple SSD - that is the drive to Erase and format as APFS with the GUID Partition Map. This applies to macOS 10.14 Mojave and above.
Once that is done >> backup out of Disk Utilities and choose install macOS.
Follow the prompts and it may automatically reboot several time.
Upon a final reboot - Setup Assist will present with the newer version of macOS.
You can use Setup Asset and point it to the Time Machine Backup Drive. This is a One Time offer. Thereafter you will need to use Migration Assist

What do you mean by "install from the beginning?"
Unless you want to install a previous macOS version, there is no need to erase the OS and reinstall. Unless you have disk corruption, it hasn't been changed at all since it was installed/updated.
Being a 2019 model, you should be able to Erase All Content & Settings to remove everything you have done to it.
You can then restore your data and apps as you see fit.
Addendum to previous posting
Extra Special Notation regarding the Touch ID equipped Apple Computer.
Which this computer does have and I missed the first time posting - sorry
