The Italian joined VR46 for the 2024 season after losing his Gresini ride to Marc Marquez for this year.
Last year's Qatar Grand Prix winner has never been part of the VR46 Academy stable, but has been encouraged by the level of support he has received from the structure so far in 2024.
"Well, let's say the structure of VR46 is huge, it's incredible," he said.
"Day by day they are surprising me more and more, because the focus of everyone is to bring everything to the rider, to protect the rider, to try to make the rider shine.
"So, it's not like a company who does it just for business. It's a team that wants to win and to give the maximum to the riders to win.
"So, it gives me a boost and confidence to push and to stay focused always.
"So, for sure with their help, I'm learning, I'm improving. I'm sure that during the year you will see some changes on my side."
Because Di Giannantonio – who sits 10th in the standings after two rounds in 2024 – is still not a VR46 Academy member, his training programme differs from that of Francesco Bagnaia, Marco Bezzecchi, Luca Marini and Franco Morbidelli.
