I was the same, really pissed off when they made the change. Luckily, it's android, so you can install a custom launcher. I remember I had to play around with adb a bit, but after that, it's smooth sailing. I use FLauncher[0], but there might be something better out there.
Another neat "pick an OS to boot into" tool I discovered recently is Ventoy [1]. You install the bootable menu on your USB drive, and then you just drop ISOs or IMGs on there to add choices.
