Get the portal block coordinates
Replace the portal blocks with air using `world.setBlockState(pos, Blocks.AIR.getDefaultState())`
If needed, remove the surrounding frame blocks manually
If the portal is a Nether portal, break one obsidian frame block to invalidate it
Call `world.updateNeighborsAlways(pos, Blocks.AIR)` after removing blocks
For custom portals, remove any tile entities or portal state data tied to the portal
Run the block removal on the server side only
Use a loop to clear every portal block in the portal area
If the portal auto-regenerates, cancel or remove the event or tick logic that recreates it
