You can do smthng like that ->

source.pre('findOneAndUpdate', function (next) {
    console.log('------------->>>>>> findOneAndUpdate: ');
    this._update.$set.objects = [];
    this._update.$set.people = [];
    this._update.$set.events =  [];
    next();
});

pay attention to _update.$set because in the context "this" will be a query. So you can easily add anything you want!
