How many m.2 slots does my laptop have?

[Kollegoli]

Hello
I tried to find out the hardest i can, but i just dont manage to find information about the motherboard of my laptop. 

I would like to install an additional SSD. I already have one and it needs to be connected to a m.2 slot (like small PCI slot) as i understand.

I dont wanna buy a special screwdriver to open my notebook just to find out if i have such slot or not, so i have to post this question here.

How many m.2 slots does my notebook have? It already has an SSD and a HDD installed.

Thanks

Thanks for your answer.

Does that mean, that i can install an additional SSD (m.2. M-key) event though i already have one SSD and one HDD installed?

Sorry, but in the specs i dont find this information anywhere. Also when i watched videos about other HP Envy notebooks with similar architecture, i understood that there is only one slot for SSD, so that you can install only one SSD at a time.
