I have found that a lot of the best info on Dwarf and Half Dwarf Burms tends to come from the UK. This is at least partly due to the Burm ban by the Lacey Act - as a lot of smaller burm breeders who had dwarfs or half dwarfs before the ban - actually got out because of that ban.
In the UK they have F3 & F4 Dwarf Burms which tend to have a temperament more like that of mainland burms. One of the best care sheets for Dwarf Burms I have found online is - from Snakes N Adders on YouTube. The 1st in his intermediate series - is on the Dwarf Burmese Python. It is a little over 9 minutes long.

Also Bob Clark has a video on taking eggs from a couple of Dwarf Burm females. And he still sells pure Dwarf Burms.
