I want to disable following stock.inventory default function using my custom module:

@api.onchange('product_id', 'location_id', 'product_uom_id', 'prod_lot_id', 'partner_id', 'package_id')
def onchange_quantity_context(self):
if self.product_id and self.location_id and self.product_id.uom_id.category_id == self.product_uom_id.category_id: # TDE FIXME: last part added because crash
self._compute_theoretical_qty()
self.product_qty = self.theoretical_qty

Anyone can help?
