Disable HRV Status

As far as I know, HRV status is disabled only when you disable all-day fitness tracking.

I am not quite sure that the HRV that's recording during sleep, influences training status. At least not in my case as far as I could tell.

I have used two Fenix 6 models (same software and a total reset beforehand) at the same time for 6 weeks, one both for 24-hr fitness tracking, sleep tracking and activities, the other only for activities (with 24-hr fitness tracking switched off). They both had the same training status after the 6 weeks. And the same max HR estimate.

The other way around, activities clearly influence nightly HRV. When I do an intense interval session close to bedtime, nightly HRV is way lower than usual.

Some drastic workarounds?

if you don't wear the watch outside of activities, stress history will be unavailable. Then, if you don't use the watch to track sleep (either by not wearing the watch or disabling the wrist HR during the night, using battery saver, for example), you will also nullify the HRV data and their impact

Training readiness will still be available without sleep, HRV and stress history, and will reflect metrics already included in the training status. You won't be able to max the training readiness, but it is still usable.

Another approach is to keep sleep and HRV tracking, but disregard training readiness and eyeball your readiness by using the body battery, the training load ratio and the recovery time.

IMO, not worth the trouble though. The training readiness is something to take at face value because HRV status has been well implemented, given the lack of accuracy of HRV in general through wrist HR. HRV will be impacted by alcohol, illness, jet lag, work/life stress and microstress and training stress.

It sucks but I may consider your first idea of not wearing the watch at certain times to nullify the feature. It’s a really cool feature, but it doesn’t work very well when you don’t have a consistent sleep and training schedule. I work 12 hour shifts overnight, so you can imagine how that impacts the data on the watch.

I have quite irregular sleep/work hours and in order for sleep tracking to work properly, I have to adjust sleep hours every few days depending on schedule. In days long past, you could start and end sleep manually on the watch (early software on Fenix 3). Was ideal.. but gone.
