I use a very handy app for this, called 'UntrackMe'. It's available on F-droid. It will send every Reddit link you click to a Redlib instance of choice. It works in most browsers, including Vanadium, Brave and Mull.
Enable Reddit to Teddit, and enter your favourite Redlib instance (I use redlib.pussthecat.org). Besides Reddit, this app will also let you replace Youtube links with Invidious, and Wikipedia links with Wikiless.
The app offers some more alternatives, but not all of them still work (like Nitter for Twitter, Bibliogram for Instagram, and Proxitok for Tiktok).
