Looking for a science rebalance mod

[Head4TheHills321]

I'm a huge fan of keeping games fairly vanilla, but there is one thing that bothers me about KSP... there's not actual reasons to do anything. I would love a mod that makes getting science require me to actually go to a variety of places without having to set personal restrictions! I would love to have to do low tech probe missions to celestial bodies in order to unlock the parts intended to be used to get crewed missions to said destinations. Just reducing the science reward for planets isn't really what I am looking for... I kinda want tech locked behind concrete goals. Is there anything like that?

I could recommend two things... kerbalism modular science... the simplex version, and also the Quartix Tech Tree, using 50% science. this techtree is designed for a pretty stock install with limited part mod support. You can choose to not have crewed flight till later in your career.
