Dual SSD Thinkpads?

I may have to get a laptop in the near future, and thinkpads seem to have the most complete package in terms of serviceability, durability and price (when bought used).

One hurdle that I've seen in popular models is not being to install a second storage drive, and I may need this for dualbooting purposes. Technically any laptop can take a second ssd if you remove the wifi card, but that makes it less usable on the go. Here's a rough idea of what else I'm looking for, besides 2 storage drive slots (doesn't matter if it's m.2 or sata):

-At least Intel 6/7/8th gen or Ryzen CPU
-Can be 14/15/16/17 inches
-Probably now a W/P series, since those are more for a GPU I don't always need on the go (and which will be harder to get working with Linux since they're nvidia)
-Around 4-6 hours battery would do it
