Your questions and concern are a valid and honorable one. I am sure there are numerous leaders struggling with this same issue. First this is probably not the answer you are going to want or like but it is probably the course of action that will get you the most bang for your buck.
Anytime a senior leader told me I had to do something that was their desire but not mandatory I bucked the system and just said “No!” They could put me on crap detail or whatever they wanted and I would comply and make my case for their violations afterwards which typically was very embarrassing for them. Now the flip side was anytime a Leader came to me and said “Hey, I need your help with this. Can you help me out?” My answer was typically “Yes” How can I help. I just wanted to be asked if it was something that was optional for me to do. When you take an optional event and turn it into a mandatory event usually you get push back. Put yourself in their shoes. Do you want someone telling you an option is a requirement and trying to shove it down your throat? Keep in mind their compliance is optional until the mandatory possession date.
