Is there anyway to use custom worker node OS or load specific kernel modules in standard worker node OS on GKE?

GKE appears to support 3 type of worker-node OSs as of writing this question (around mid Aug'2021) i.e. Container optimized OS, Ubuntu, Windows. So my questions are:

  • Is there a way (or a workaround) that lets one use RHEL as worker-node OS on GKE ?
  • Is there a way (or a workaround) to load a kernel module (s.a. modprobe sctp) into worker-node OS on GKE, say while working with Ubuntu as the worker-node OS ?

Here the stress on on GKE is to emphasize that I'd like to use GKE as a managed CaaS service.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
