It's quite simple, just use the "AND" so you can include multiple nodes, and use the "NOT" node for things that could disable your ability.
Here's an example using the ghost's activated cloaking ability being disabled by researching permanent cloaking.

quite simple.
Use the NOT argument.
So using ability requires X upgrade, but you can add the very same thing but put NOT, on top.
Look at how all upgrades use the not argument as part of their requirements.
