Using different GPUs on single board

I have 1 old Geforce GT 710 and a new RTX 2070 super (MSI).
I use Linux (Ubuntu preferably). I would like to use both the Graphics card at once.
How can I go going about that.?
I have 2 monitors I still want to be able to use both.
Use cases include being able to launch dedicated RTX 2070 for new virtual machines or for Tensorflow training. and other (GT 710) for rendering desktop(2 monitors I have). also I have H170-PRO mother board with built in Intel graphics card.
CPU i7 6700
