I presume the term nonviolent refers to physical intervention techniques that do not involve the application of pain to the subject.
Any physical intervention MUST be justified, even techniques that do not involve the use of pain. If physical intervention becomes a necessary measure, a person may use force that is proportionate to the circumstances they are facing. If they are dealing with an individual that is offering low level resistence, it could be argued that dropping them to the floor and kneeling on them could be excessive. This measure, however, could be entirely proportionate if the same person is offering high level violence.
All of this falls under the banner of 'Use of Force', along with Self Defence and Restraint. Further information can be found here covictrainingsolutions.co.uk/what-is-self-defence

Firstly, physical intervention falls under the banner of 'Use of Force', and all use of force must be jsutified in the same manner, whether it be self defence, restraint, or the defence of others. The first question a person must ask themself would be "is physical intervention necessary?". By that I mean is it the only tactical option to resolve the situation at hand? Has the individual attempted verbally de-escalating the situation, is verbal de-escalation even a credible option at this stage? It is all down to the situation as the individual perceives it at that point in time. If physical force is necessary, then the level of force used must be proportionate.
