I am currently using a Samsung Note 10+.
I recently became much more concerned about privacy and have seen a lot of info about grapheneos and lineageos. In my research I found that neither support my phone.
What can I do to increase my privacy without getting a new phone?
The only change I have made so far is that I now use duckduckgo.

GrapheneOS would require a Google Pixel phone, 2 or higher I think, or if you're good you could roll your own, they offer the code.
I'd disable location services, and see if LineageOS has a rom for your model, and get to using it. Also, familiarize yourself with how the whole "custom rom" thing works, last thing you want is to load a custom rom that hasn't been updated in 2 years, or not know how to update your own.
There's probably tons of posts and guides about different settings or firewall apps to use.
-Pay for a VPN and use it, get off any and every google service, facebook product, and for that matter all that social media stuff.
Look online about how to use adb to remove apps and remove facebook and everything google/samsung you fell like you can live without. Maybe root and use afwall+ (fdroid) to allow network access to a limited number of appd.
Root is a major security attack surface increase. It should be avoided. Afwall+ can be bypassed and is a false sense of security.
The adb disabling advice is good though
Why is root a security attack? Don't apps need explicit permission from the user to have root privileges?
All you need you can do via adb. No root required!
