How do I reflash both partitions of a Google Pixel 6 Pro device in one go?

How do I re-flash both partitions of a Google Pixel 6 Pro device in one go? If I follow the instructions at https://developers.google.com/android/images , I have to: 1. re-flash the first, default partition (a or b) using flash-all.bat 2. return to the bootloader (which means either (A) turning the device off after it automatically reboots and booting back into the bootloader using the hardware buttons or (B) doing a "false setup" of the device (after it automatically reboots) and returning to the bootloader via Android's Developer Options screen and the adb reboot bootloader command 3. set the inactive partition to the active partition using fastboot set_active a or fastboot set_active b 4. re-flash the second, remaining partition using flash-all.bat Is there a way to combine these re-flashing steps to make re-flashing both partitions less troublesome? (Note: My goal with re-flashing both partitions instead of one is to eliminate malware, so simply nuking and regenerating both partitions from scratch would also be a workable solution, but I don't know how to do that either.)
