Might give the Minsc comics a look...... Not a huge fan of Minsc but BG3 related..
Yes, Mindbreaker is the final adventure that ties into BG3. And Infernal Tides is the one before that and relates to Descent Into Avernus, which also has ties into BG3, though I don’t know whether the events of either story will be considered canon for BG3.
You could dive straight in to one or both of those stories, if you’re not particularly fussed about getting to know the characters first. I don’t think it would be particularly hard to pick things up as you go.
