You could install DivestOS, it's a more secure OS build on top of Lineage. Here's the link for your device if you want to check it out: https://divestos.org/pages/devices#device-vayu

Which Poco is it?

Can't you remove it with the Universal Android Debloater or just flash a custom ROM?

Is it open source?

Your OS has lots of other weaknesses (literally) though. GrapheneOS is the way to go, DivestOS is another option.

Have you tried the Universal Android Debloater?

Great option on desktop. For mobile devices, I recommend GrapheneOS, it's Android without all the proprietary Google bullshit and with massive privacy/security improvements.

What exactly are you referring to?

Time in terms of setting everything up or learning how to use it? Because I can tell you that both are relatively easy. The installation is super easy, no harder than an ordinary Windows setup. The Steam Deck by default uses a desktop environment called KDE, as a Windows user, you should feel right at home. I'd say it's very intuitive to use and easy to learn. As Bazzite tries to mimic the Steam Deck experience as closely as possible, it uses the exact same stuff. Maybe check out this video.

You can always dual-boot. Bazzite is a very stable Linux distro, which is optimized for gaming and basically gives you the same experience you would get on a Steam Deck. I highly recommend it.
