Drivers have expressed their surprise that a fourth DRS zone has not been added on the revised back straight amid concerns over a lack of overtaking at the Marina Bay circuit.
A layout change is owed to construction work around the final sector, which has led to the characteristic 90-degree Turns 16-19 being replaced by a long straight with a high-speed kink.
Drivers plan to use the Friday briefing to lobby the FIA for an extra DRS zone, but any trial for FP1 is extremely unlikely to be given the green light due to safety concerns over its last-minute nature.
However, the FIA has said that it was originally willing to embrace changes to the configuration but that there was no "clear consensus" when teams were consulted in advance of this weekend's race.
A statement supplied to Autosport read: "We won't be assessing any additional DRS zones for the Singapore Grand Prix.
"It is something that was considered following the change in layout for this year, and the FIA contacted all of the teams several weeks ago to ask for their feedback and input.
"There was, however, no clear consensus from those teams that responded and, following our safety simulations, it was decided that we wouldn't take the matter any further."
Autosport understands that not all teams responded to the governing body and that the consultation period began months in advance.
