A/B devices: Switch slots without using PC

I've seen this question asked two years ago https://android.stackexchange.com/q/245205/131553 which asks for the same on Android 9,but with so many tools being developed (and abandoned) and changes in Android versions , is it possible now? I use Pixel 4a/6a, rooted, Magisk 25.2 on Android 13. There aren't any TWRP recoveries for them. With the perpetual cat and mouse game between root detection by banking and such like apps, I feel the cat (Google) will have an upper hand soon. So my thought is to have one slot rooted and the other slot unrooted and on the fly switch slots using an Android based way. I know it can be done using a PC but that's not what I want. Does anyone know of any way? Maybe Termux based or some kind of scripting? Or Magisk/Edxposed modules? I don't want multi-ROM or dual booting solutions (doubt if they exist for current Android versions) Edit 1. [Switch My Slot](https://github.com/gibcheesepuffs/Switch-My-Slot-Android) hasn't been updated after 2021. When I run that it closes saying bootctl binary missing 2. [Magisk Bootctl Binary](https://github.com/roihershberg/bootctl-binary) works only upto Android 12. I tried it but there appear to be some Magisk limitations too apart from failing since it is not designed for current API level. 3. I couldn't find any bootctl Magisk module in various repos
