It's tricky I think because even if he can learn to program to a suitable standard, I think the reality will be that people will see him as a "junior" but you will have a different working dynamic since it is easier for an e.g. 30 year old to coach someone who is younger if they are doing it wrong but could be tricky trying to coach an older person unless they have genuine humility, otherwise your dad might feel patronised or be offended by some youngster without the experience to coach well.
Another avenue, if it is just the industry he likes rather than programming specifically, he could probably get more distance by utilising his exec skills to do a technical management role like Product Manager, Product Owner or Project Manager. He could then get as much exposure to the programming as he wants without needing to produce as much of it as would be expected of a dev.
At risk of getting flamed...

Don't know, just thinking out loud.
