Would I be able to disable parts of 1.17 update?

I have been seeing a lot of the 1.17 snapshots, and I am a huge fan of the Cliffs parts of the update, but I think the new caves would be very annoying and hard to light up. Would I be able to download the 1.17 update but disable the new cave generations. Ideally, I would disable all cave generation, but probably keep ravines to help me out early game. The idea is that I would no longer have to light up caves, or when I am mining for diamonds, I would not have to bridge across or deal with lava. (I am pretty sure that lava generation is tied to cave generation.)

Workaround 1: Fullbright

In your video settings in minecraft there is a brightness slider, you can go into the file storing this and change it to a really high number, so you will always be able to see with no light.

Workaround 2: amplified world

Download the latest minecraft snapshot and open it. Click on create new world -> more world settings -> world type -> amplified

This will give you massive mountains and the *normal small cave generation, with all 1.17 features currently released in snapshots.

*It is currently unknown if it will be possible to disable the new cave gen in 1.18, and in the snapshots with cave gen features there was no built in way, so i assume datapacks will be needed upon 1.18's release

Using Fullbright or world type Amplified is a good workaround, or keep stacks of torches on you at all times to keep the game as vanilla-ish as possible to feel more legit. (Coal and wood are easy to find, so you will have plenty of materials to make torches, considering the recipe makes 4 of them.)
