Help mixing GPUs

I’m new to mining and started my gaming laptop with an nvidia gpu (I know laptops aren’t made or recommended for this, but that’s what I have these days). I found a good opportunity to get an EGPU with a 5700XT at a great price. Would it be possible to mine with both GPUs or would it generate some conflict? I just want to increase my profits a little while learning before investing in a dedicated rig.
