I have seen no recent reports of them issuing a non-o visa for retirement
I suggest you contact the consulate in Penang about the non-o visa.
It seems their website is incomplete since all those shown on the list takes you to the main page of the website when you click the link.
For the embassy in Kuala Lumpur it appears they may be only issuing them for citizens or residents Myanmar. I suggest you contact them as well.
