That's correct, there can only be one switcheroo handler, first to
register wins.

That means a handler was already registered.

Don't forget to rebuild your initramfs and also fix the modprobe.d
line that manually loads asus-switcher before nouveau (you probably
just want to convert that to byo-switcheroo).

The fixes those modules apply are still relevant, so if you want them,
yes.  To recap on their purpose; i915-jprobe prevents the lid notifier
running when switch to discrete graphics.  If you have intel
integrated graphics and want to use DIS > switch, you need this.
nouveau-jprobe disable the nouveau interrupt handler while the device
is powered off, so if you want to use integrated graphics and nouveau
is loaded for your discrete graphics, you want this.  Thanks,
