installOverrideList

An https URL or an Amazon Simple Storage Service (Amazon S3) path-style URL to a list of patches to be installed. This patch installation list, which you maintain in an S3 bucket in YAML format and specify in the SSM document AWS-RunPatchBaseline, overrides the patches specified by the default patch baseline.
