I think this is a dangerous way to approach the problem. Regardless of whether or not the assertion that the "primary factor is they know how", the underlying cause is distress and hopelessness.
I'm frustrated a bit by how discussions of suicide — with vets as well as others — tends to focus on making the means less available, as if it just solves the problem. That's a solution for society, to wash their hands of addressing the underling problems, and not a solution for the person suffering.
Veterinarians should be in a position where they don't want to commit suicide, regardless of whether they have the means.
