Open the world to the network and turn on the cheats, then turn on survival and re-enter, the cheats will disappear and the world will return (if it is not deleted)
I've done so much netherite digging, I actually enjoy it. TNT is a good trick, but getting the materials and crafting it takes time. Lighting it and running back and forth takes more time. Yes it blows a big chunk, but with an axe with efficiency 5 blasts through everything so fast you'll get about the same amount of blocks cleared as you would with TNT in the time it takes. But you also need unbreaking and mending, but with all the gold and fossils you don't have to worry about XP for repairs. If you hit lava just dig a hole under it and its contained. Unlike the TNT method blasting into an ocean of lava. I average about 8 or 9 debris every 30mins or so, I think that's worth the effort. That's just what seemed to work best for me.
