Any other methods Better than PSA to monitor prostate cancer?

I've attached my PSA scores since they started saving in EPIC in 2000. While you can seen a marked increase around 2017, my Family Medicine Dr. said it was age related and well within the norms. Having read other's numbers, you could make a case that my numbers have always been low. We decided on an MRI in 2022 just for 'sh*** and grins' so to speak. I couldn't accept the PI-RADS 5 result and followed up with a confirming MRI shortly thereafter. My faith in PSA, as a solid indicator of PCa, was badly shaken.

My TPUS revealed G: 4+3=7 in one core with some risk factors and I began a tri-modal treatment plan (Orgovyx 4 months; Cyberknife Boost and VMAT). The later treatment is currently underway, 5/25 completed.

I continue to query Drs. and other sources about how to monitor progress and determine if any cancer will be remaining after the conclusion of my treatments. The only answer that I'm hearing is that
we'll be monitoring my PSA. You've probably guessed my question by now. I have very little faith in PSA and wish that I discovered my cancer years earlier. Has anyone heard of other methods to know the state of our PCas, hopefully zero, post treatment? I'm thinking I might have to buy a Ouija Board;-) Kindly advise.
