High insulin, being obese and high BP are greater risk factors than the LDL cholesterol numbers. Many of us have researched this to "death" if you excuse my choice of words. LDL is bad if it gets oxidised / damaged (the best method of doing this is a carb heavy diet), LDL "fixes" damage within the arteries, so the issue is to resolve the underlying health issue which LDL is trying to patch up.
If you are still concerned and want to straddle the line between current advice and accepting that HDL being high is more important, as well as lowering Triglycerides, walking and physical exercise can reduce LDL, reducing dairy a little and adding usual LCHF / Keto fats (I add and use butter, MCT oil for pancakes, I drink fresh coconut water, and reject the guidelines).
I would recommend YouTube, swat up on the Dave Feldman Protocol (this will show the variability of cholesterol numbers and what influences these). You might also want to watch Ivor Cummins, Dr. Paul Mason and Nina Teicholz, and research Ancel Keys and the 7 countries study. If you do these things, you will have choices about the science and where you should place your trust i.e. lowering cholesterol based on the ideas of Ancel Keys and others, when your body makes circa 85% naturally and your brain is made of 25%, or that other risk factors under your control reduce your risk of CVD / CHD even when using the risk calculators the NHS use.
