I've already posted this a few times but I figured I would try to save some people time who want/need to root from any security patch. This is a copy and paste from an answer I gave in another thread but it's a basic how to.

Install DSU sideloader app from playstore to boot a prerooted GSI then use Partitions Backup and Restore app from playstore to save copies on your device. Install magisk app and patch the extracted boot.img and then transfer backups along with the patched boot image to your PC for safekeeping and flash the patched boot.img in fastboot. You can rename any .bin files to .img to flash them if they get extracted as a .bin file. Check your settings in the partitions Backup and Restore app before starting the backup process. You can choose to save them in an easy to find directory and for me it was better to choose to save them RAW/uncompressed then just compress them all into a single archive rather than having a hundred separate archives for each individual partition because it makes it easier if you have to reflash things if you need to recover. You may want to disable battery optimization for the app because it takes a while to extract all the images doing a full backup but its well worth the wait time if it saves you from a brick later on.

I wish I had time to elaborate but hopefully someone else can take the time to elaborate and add to this for anyone needing step by step. I'm surprised nobody has done this already.

Credits to AndyYan for giving advice on the root method. I stole this from him and just made a post with a title that makes it easier to find since so many are still asking how to go about rooting their devices.

*****REQUEST TO COMMUNITY********

There are many who are already on August Security patch and i dont have time to update and post the newest images. So if you are on august patch and pull backups I ask that someone please be so kind as to upload a copy of your backup to Google Drive or a filehosting server of choice and post a new thread so that others can unbrick their devices.

*Please ***DO NOT include**** the following partitions*:

DEVINFO

DINFO

FRP

KEYMASTER_A

KEYMASTER_B

KEYSTORE

LOGDUMP

***MDM1M9KEFS1

***MDM1M9KEFS2

***MDM1M9KEFS3

***MDM1M9KEFS4

MODEMDUMP

OPLUS_SEC_A

OPLUS_SEC_B

RAWDUMP

SECDATA

STORSEC

USERDATA

VM-KEYSTORE

*** These partitions may/contain YOUR personal device info, DO NOT make these public***

You can make a new Google account for the sole purpose of uploading these for the community so as not to fill your own GDrive. Be sure to change permissions for the images to share with anyone who has the link. This would be very much appreciated by many.

Thanks to ctschrodinger88 & dmtec for posting more detailed instructions!!! you can find ctschrodinger88's instructions below, scroll down to the 5th post.

dmtec also posted instructions in another thread linked here: https://xdaforums.com/t/august-boot-img.4491831/post-87426877

we are still in need of august modems if anyone cares to upload them to their drive and link them or any other filehosting service.
