Instinct Tactical is not listed as a a watch that supports wrist heart rate during swimming: https://support.garmin.com/en-US/?faq=kbOXNev7NS4DQcc3IjAV49
e7andy is right, but there are some hacks possible. First of all you could record your swim as another type of activity, and then changing the type subsequently in Garmin Connect. Then you could downgrade the firmware to v10.72 - Garmin forgot to disable the HRM at swimming in that version (see the thread Heart rate with swimming now works? - Instinct - Wearables - Garmin Forums). And then, there used to be the following hack available (not sure whether it still works): My "hack" to enable heart rate during pool swimming - Instinct - Wearables - Garmin Forums
