There are teas with very strong flavours, as other have mentioned.
Matcha ( Japanese powdered green tea ), houji-cha ( roasted green tea ), mugi-cha ( barley tea ), et al.
You're out of luck avoiding acrylamide though, as most teas have it as well.
There is a study about amounts of it in black vs green and other different types, but honestly, avoiding acrylamide in general is not just very difficult, but also not very useful considering as others have said something like the particulate matter in air or metals and PFAS in water.
Getting good air and water filters would be doing much more for your health than radically altering your diet to avoid all baked goods, bread, cacao, all teas, coffee and whatnot.
