After installing the Nether Portal Spread 1.17.1-1.12.2 tweak-mod, the portal to the Nether World will gradually replace some of the blocks around the portal with different blocks from Nether, such as: hellstone, quartz ore, hell brick and even soulsand blocks.
A little imbalance tweak, but it is very realistic, because the matter that is near the portals must move to another dimension. So you can just wait in a safe normal world for teleportation of these blocks and just get it, while not risking the life of your character.
