If you want more security, you'd better get a monitor controller or attenuators so that doesn't happen:

You can also use an ADI-2 Pro FS R BE as a monitor controller, because the converter has a gain pot, that doesn't just set itself to 0dB and with the device you still have some useful additional features.
You can also first try out whether you find a setting with the existing devices, which is still bearable at 0dB.
So first adjust the HW output AN 1/2 down to about -40dB, so that it is in a safe range. It's best to save this setting on all 8 snapshots, so that you don't accidentally select another one and it suddenly becomes unpleasantly loud.
About the settings: so use the lowest output level at the output AN1/2 and choose the least sensitive setting at the input of the active monitors. You will hear it when it gets louder or quieter ....
And when both are in the "quietest position", try to move the fader of HW Output AN 1/2 slowly towards 0dB.
If it is still too loud, which I fear, then you have to work with 20 or 30dB attenuators or loop in a monitor controller or (best of all) invest in an ADI-2 Pro.
I would use a music player to get some music for volume test.
This is e.g. a nice attenuator, which you can set to -10, -20, -30 dB: https://www.thomann.de/de/jts_ma_123.htm
I also recommend the use of a SPL Measuring Device, this one is a nice one, which is not too expensive.

This way you can control, whether the volume stays is acceptable range for you.
There are several articles in the internet what a good volume is for mixing and mastering music.
