As far as I know, we can't. You'll have to be careful not to get into a disadvantageous position.
More advanced spells don't always require gestures, though.
Should all else fail, the bond between a shinki and a god is a mutual one, and blight is significantly more painful to the god than to the shinki. The sort of god who would name you for convenience against your will is likely also the sort of god who would release you if they found themselves severely blighted in response.
[Shinki do have options... even if one of those options is effectively a threat to drag a god down to destruction with them.]
