To get to the sea emperor inside the facility you have to "play" in creative mode i guess. In freedom und survival you are stuck after the thermal plant in the lava castle. But when you are not even in the inactive lava zone, i guess you are at least one step earlier.
Did you explore the facility in the lost river? The one with the warper specimen? If so, your next step will be the thermal plant, and for that you have to dive deeper than 900 meter, so the seamoth can't be used for this. You will need a prawn suit and/or cyclops.

Warning: Big spoilers ahead. Only follow what you must need to know. Then stop.
Getting near the cure needs cheating as the last part is sealed from the normal game.
The path only shows the way and doesn't include any preparation for depth and creature handling.

You need to find the Precursor gun first to find a signal there inside the halls.

You need to find the Lost River second, which you can find by following the signal found inside the Precursor gun.

Then you can get the Thermal plant facility signal there that will lead you to a big mountain in the lava zone.

Around that mountain are 2 holes leading down to a big lava sea zone with the PCF at the end.
The PCF is sealed by force fields, so you need to cheat you inside. Once finished it can be officially entered with the blue Precursor key.
