Process of upgrading VxRail VCSA & ESXi Versions?

Hey folks,

I've been attempting to look up information on what exactly we need to do in order to upgrade our VxRail environment, specifically VCSA as well as ESXi versions. There are two vulnerabilities that I would like to mitigate:

VCSA: VMSA-2021-0020.1 (https://www.vmware.com/security/advisories/VMSA-2021-0020.html)
ESXi: VMSA-2022-0004 (https://www.vmware.com/security/advisories/VMSA-2022-0004.html)

Our current VxRail environment consists of 4 hosts (3x S470 / 1x S570) and is reported as VxRail Version 4.7.530-26975664.

I've been scouring Solve's website regarding trying to find information about how to upgrade everything; the order of things to upgrade, where to obtain the files, etc but I haven't been able to find anything. Our environment is completely offline, so I would have to download the files and transfer them to the VxRail to upgrade.

Does anyone have any pointers on where I can go to find this information so that we can upgrade things? 

Thanks!
