I don't know exactly what it stands for, but I believe it is directly related to the fuel system counter-measure Toyota came up with. Here from Toyota's post-race press release:

Nerves were stretched in the TOYOTA GAZOO Racing garage as the final quarter of the race approached. An issue on the fuel system of the #8 car prevented it completing full stints. Over consecutive fuel stops, it returned to the pits earlier each time as the team worked intensively to find a solution.
With four laps in hand over the third-placed Alpine, and no prospect of a quick repair, a remarkable team effort tested several options until an effective counter-measure was developed. The drivers had to activate a specific setting at defined points around the track to return the #8 car to normal stint lengths.
That proved even more crucial when the #7 developed a similar issue. Kamui and then José could quickly manage the situation and maintain a comfortable lead. Close communication between drivers and race engineers on both cars ensured the issue was kept under control.

DDef must have been used to activate the 'specific setting' (counter-measure) in order to maintain relatively reasonable stint lengths and stay on track. Also according to Toyota's press release, Akio Toyoda said that apparently Buemi helped come up with the counter-measure to the fuel system issue.
