Set my blue switch to pair without factory reset

Hi all,
I’ve had my blue series switch for a while and happy. I’m thinking of switching from SmartThings to Alexa, is there a way to set the switch to pairing mode WITHOUT factory reset? I took some time to configure it with the right light intensity to work with my bulb and also for 3-way and I would rather not do it again.

I saw the instructions at Setup Instructions | Blue Series Smart 2-1 Switch (On/Off & Dimmer) - Amazon Echo, they explain how to put the switch in pairing mode, but I’m not clear if it will ALSO factory reset the device

Bonus question: if I switch to Alexa will I get access to the advanced settings such as controlling the LED and the “throttle” for the light bulb?

I’m considering dumping SmartThings after nearly 10 years because the hub is giving me weird issues (2 days ago all devices stopped working even though I can see them in the app and if I manually press the paddle on switch the events are visible in the app, but I can’t control ANY device from the app)

Bump to see if anyone knows

This isn’t a definitive answer, but I was looking for the same info a few months ago and never found anything. I ended up documenting my settings and factory resetting.
