Compliant press fit pins have to have a tapered end or the barrel will be damaged during insertion.
Starting with a PCB thickness of .031", you would not have enough contact surface area for a reliable connection and strength against creep issues from insertion and extraction pressures.
Since the vendor of the part specifies the design won't work that leaves you with either:
-buying the thru-hole version and soldering it or
- if the major reason for the compliant pin design is to assure the part stays flat and properly aligned then use it but solder the pins afterwards to achieve the reliability.
- The only other choice may be to use an SMT socket for your part if total height isn't an issue.
I hope this helps.

Do you mean compliant pin pressfit connectors, or test points, or pins
for CCGAs?

Subject: [TN] Compliant Pin & 0.031 PCB
Anyone using compliant pins on 0.031" PCB's? If so, what PCB finish? We
have
a product team who wants to use this combination. To my knowledge, there
are no pin suppliers who will recommend their pins with this PCB
thickness.
