So I wanted to give carpet skyadditions a try after watching a couple videos from Ilmango. However, while I agree with him about not using the Oak tree at the start, I really dislike the orange tint of Acacia. How would I go about changing it to say…spruce?

I know I can join in creative break the Oak down, plant and bonemeal a spruce and rejoin normally, however that messes up my advancements. Any way to reset them completely? Also, i see one of the first advancements is to get an oak log. Do I need a custom datapack to change it to spruce log?
