@lakeview You made a post, so that's a start! Next step is to write your question in the body of the post, not the title, so you'll have more space.
I've never downgraded Android so I can't help, but someone will be along who can. Keep the faith, you'll get there!

@lakeview Hello lakeview,
I quote from https://devices.ubuntu-touch.io/device/bonito/ :
"You can install Ubuntu Touch on this device using the UBports Installer on your computer.
Make sure the bootloader of your device is unlocked and that your device has the required version of Android installed. Before installing, follow the device-specific instructions below:- Make sure it is NOT the verizon model, as that model does not allow the bootloader to be unlocked.
- If the device is running an Android version above 9.0, you have to downgrade to the last 9.0 release. Make sure to revert to factory image PQ3B.190801.002 before continuing."
So for the factory image you need to go to https://developers.google.com/android/images#bonito . There you probably have to click on "Acknowledge [I have read and agree with the terms and conditions.]" and than you look at a long list for the factory image (PQ3B.190801.002 for the Pixel 3a XL "bonito").
Here are detailed step by step instructions: https://forums.ubports.com/topic/10906/ut-installation-on-google-pixel-3a-step-by-step
And for a video tutorial to unlock the bootloader and installing the image, you can check out: https://www.youtube.com/watch?v=CdNGSdYCaDY (but please be aware that you need the image for bonito and not for sargo)
All of this will only work, if your device allows you to unlock the bootloader. One comment under the linked video explains: "Some more elaboration after further research. If you have a Pixel 3a/XL with an IMEI that does not begin with 35, then you are good to go: this phone is not a Verizon model and it will be possible to enable OEM Unlock. If the IMEI does begin with 35, then it might be a Verizon model, but you need more info to determine that. One way is if you have the original box. If the box lists two IMEI numbers and one eSIM number, then it is not a Verizon phone and it will be OEM unlockable. If it lists a SIM number, then it is Verizon, and will not be OEM unlockable.
If you don't have the original box, you can go to Google Store Website > Repairs > Get Started, and enter the IMEI number. If there is no mention of Verizon in the device information, then you should be good to go with an OEM unlockable device.Hope this is useful for anyone looking for a second hand device to do this installation."
