The only way to get around the court is to amend the constitution itself.

That's not actually the case. The Constitution says this about the court system.

Article III - Section 2.

The judicial power shall extend to all cases, in law and equity, arising under this Constitution, the laws of the United States, and treaties made, or which shall be made, under their authority;--to all cases affecting ambassadors, other public ministers and consuls;--to all cases of admiralty and maritime jurisdiction;--to controversies to which the United States shall be a party;--to controversies between two or more states;--between a state and citizens of another state;--between citizens of different states;--between citizens of the same state claiming lands under grants of different states, and between a state, or the citizens thereof, and foreign states, citizens or subjects.

In all cases affecting ambassadors, other public ministers and consuls, and those in which a state shall be party, the Supreme Court shall have original jurisdiction. In all the other cases before mentioned, the Supreme Court shall have appellate jurisdiction, both as to law and fact, with such exceptions, and under such regulations as the Congress shall make.

Emphasis mine. The inferior courts have jurisdiction over all matters other than "cases affecting ambassadors, other public ministers and consuls, and those in which a state shall be party." For those, SCOTUS has original jurisdiction. SCOTUS handles appeals to the judgements of the inferior courts "with such exceptions, and under such regulations as the Congress shall make."

We do not need to amend the constitution to rein in SCOTUS. Congress, under the this article of the constitution, Congress has the authority to create legislation that limits the power of the supreme court on all matters other than "cases affecting ambassadors, other public ministers and consuls, and those in which a state shall be party." Congress can increase the size of the court allowing the current president to add judges. They can add term limits and other limits to SCOTUS. The problem is that one party doesn't want to fix the problem and that party is running the House and obstructing the Senate thanks to the filibuster rule. If we had a functioning Congress, we could pass regulations forcing the justices to abide by ethics rules. We could make it illegal for justices to accept gifts from billionaires.

Sadly, this will not happen without a Democratic controlled House and a Senate with at lease 60 actual Democratic Senators, and a Democrat in the White House. Still far more likely than a Constitutional Amendment, though.
