Is there anyway to update the configmap data part from powershell?

There is powershell-yaml but you probably want to call yq from Powershell instead because yq can keep the config value a literal block scalar while using powershell-yaml will probably convert it to a double-quoted scalar. See this question for some background on that.

If you want to change the content of the config value, mind that from a YAML perspective, it is a single scalar. The key/value separation with = is not something YAML recognizes. yq provides regex replacement in scalars which may or may not be sufficient for your use-case.
