Triglycerides are fine but LDL is too high?

I have been trying to lower my LDL for a while now but it continues to rise. My HDL is fine and my triglycerides are low, but my LDL is a problem child.

HDL: 50 TRI: 63 LDL: 173

From my understanding, it’s almost impossible to lower LDL specifically through supplements? Omega-3s it seems will lower triglycerides (not my issue) but raise LDL.

What the heck do I do then?
