This is one term I frequently come across with this sense used in FR docs; when 'overridden' has the sense of 'forcing' something to do something different from what it would eitherwise have done.
However, in the specific sentence you have, this would require some re-working to fit it in properly, since you can only really 'forcer' some specific operation etc., and you case here is slightly skewed from that.

'outrepasser' might be a better term to fit in, or even 'contourner', if the sense her is 'bypassing' the automatic control to control it manually.

English term (edited): overridden

A manual override (MO) or manual analog override (MAO) is a mechanism wherein control is taken from an automated systemand given to the user. For example, a manual override in photography refers to the ability for the human photographer to turn off the automatic aperture sizing, automatic focusing, or any other automated system on the camera.[1]

Some manual overrides can be used to veto an automated system's judgment when the system is in error. An example of this is a printer's ink level detection: in one case, a researcher found that when he overrode the system, up to 38% more pages could be printed at good quality by the printer than the automated system would have allowed.[2]

Automated systems are becoming increasingly common and integrated into everyday objects such as automobiles and domestic appliances. This development of ubiquitous computing raises general issues of policy and law about the need for manual overrides for matters of great importance such as life-threatening situations and major economic decisions.
