Short answer: not really.
Welcome, sir; I commend you for seeking and asking for information.
It's my belief one can't really obtain decent skills by just dry practice/simulation with a non-firearm. Perhaps it's a little like putting someone in a driving simulator and then telling them good luck on the parking lot/street/highway.
@Clusterfrack is right; safe handling and living with the firearm is the first priority. I can show someone how to manipulate, load and most importantly, unload safely with a simulated piece or a live gun and dummy rounds. I can demonstrate the fundamentals, but it takes life fire to confirm(and coincidentally to build confidence).
I think it was @HCM who said a little while ago that his organization was seeing good results starting with a dot, but I don't think a dot is critical. The students are also firing live ammunition in a controlled environment with supervision and coaching.
Claude Werner, aka the "Tactical Professor" has had a couple of online programs the past two years on Patreon. Even this involves live fire confirmation/evaluation. I would recommend you bite the bullet-pun intended-and get some instruction first. You'll be far ahead of a lot of gun owners if you do.
Last personal anecdote: I had firearms for years before I went to a pistol class decades ago. I had some safety/marksmanship training in the Boy Scouts. A John Farnam class saved me a lot of time and probably grief. It doesn't have to be a "name" instructor/school, but please get some. Best of luck in your journey
