The U.S. Constitution cannot be changed without a Constitutional amendment by two-thirds majority vote in both the House of Representatives and the Senate or by a constitutional convention called for by two-thirds of the State legislatures.

The constitution is what states that if at least 3 states repeal their electoral vores, then it goes to a vote. There have already been at least 4 states that have reported that if fraud is found they will take back their electoral votes and make the Senate vote. and as per the constitution, they have to vote by the majority of counties in their respective states. This has been discussed to death by different Senators and governing bodies. The Constitution covers it, which is why everything must be shown according to the rule of law.
