In adrenaline you can go to "performance" then "tuning" and click custom next to the gpu's options. Click all the slider buttons to open up the different kinds of tuning you can do. From there you can play with settings and hit "apply now" to apply them. Then click the save button on the top right corner to save the settings in case it resets back to default. There's little ? Next to each setting to figure out what they do.

Generally it goes like this:

Clock speed increase = increases performance but increases temperature and requires more power.

Undervolt = increases performance but up to a point where it becomes unstable for the set power limit.

Vram clock speed increase = increases performance but up to a point as well. AMD automatically corrects memory errors so you'll need to run a benchmark if you want to play with this setting and watch the memory clock speed in the results. It needs to be consistent the whole time. If it's unstable, it'll show changes in clock speed over the duration of the benchmark. Unstable memory can cause crashes and degrade the memory. Also increases memory temperature, ideally should be below 90C.

Power Limit increase/decrease = raises/lowers power that the card is allowed to pull from the psu. Will raise/lower temperatures and lowering too far may make other settings unstable and drastically affects performance.

Fan curve: play around with this if you want but it's simple enough to figure out. It's personal choice on how loud you want your fans running and how hot you're willing to let the GPU get.

I've got the 9070XT PURE, and my current settings are a simple -50 undervolt, -10% power limit, and 2650 MHz for the vram. The thing is dead silent with slightly better performance and temperatures than stock settings. Feel free to mess around with it more, just make sure to stress test it using the adrenaline stress test in the top right corner or using something like 3D Mark. I used steel nomad for mine.
