В 2022-м году в Формуле 1 изменится регламент на коробки передач

Спасибо, нашёл ответ на свой вопрос - "нет". В '22 году можно будет один раз изменить передаточные, заявленные перед началом сезона.

Пока (в предварительной версии регламента на 22-й год) да. У разных производителей могут, у производителя и клиента - не могут.

9.7 Gear ratios
9.7.1 The number of forward gear ratios must be 8. Continuously variable transmission systems are not permitted.
9.7.2 Each Competitor must nominate the forward gear ratios (calculated from engine crankshaft to drive shafts) to be employed within their gearbox. These nominations must be declared to the FIA technical delegate at or before the first Competition of the Championship.
In the event the Competitor obtains the Gearbox from another Competitor as a TRC, the gear ratios used must be the same between those two Competitors.
During 2022 only, the selected forward gear ratios may be changed once during the Championship Season.
For the avoidance of doubt, changes to the forward gear ratios under the provisions of this Article may involve changes to either the gear ratio pairs defined in Article 9.7.3, or to the final drive.
9.7.3 No forward gear ratio pair may be:
a. Less than 12mm wide when measured across the gear tooth at the root diameter or any point 1mm above or below the root diameter. Above this area each side of the gear teeth may be chamfered by a maximum of 10˚. In addition, a chamfer or radius
not exceeding 2.0mm may be applied to the sides and the tip of the teeth.
b. Less than 600g in mass (excluding any integral shaft or collar). If an integral shaft or collar is to be excluded the mass of this may be shown by calculation assuming the gear to be 12mm wide and the shaft geometry to be the same as that where slide on gears are used.
9.7.4 Gear ratio pairs must be made from steel.
