How to upgrade vSphere stemcell to hardware version 9

Is there a way to upgrade a vSphere stemcell to hardware version 9.

Our current issue with hardware version 8 is the missing CPU instruction rdrand.
Based on the post https://content.pivotal.io/blog/challenges-with-randomness-in-multi-tenant-linux-container-platforms this would allow us to use /dev/random and never be blocked due to the entropy pool being empty.

We are currently experiencing the issue discussed in the pivotal blog post about containers blocked on /dev/random and failing to start.
