[Feature Request] Env variable to disable ESTS-R #5223
Description
MSAL client type
Confidential
Problem statement
Some Azure system build out happens before ESTS-R and teams have to do a 2 pass buildout. 1st with regional endpoint disabled and then laster when ESTS-R becomes available with regional endpoint enabled.
MSAL has a flag to do this per instance but there are multiple wrappers that mask it. Ex PDP plugin in MISE wraps it and has its own different variable to set to use global vs regional ests.
Instead of chasing these different configs having a global configuration / env variable would make it easy for services to enable or disable the setting.
Proposed Solution
If env variable MSAL_DISABLE_REGION is set (to any value), then all ESTS-R logic will be ignored.
This option overrides all other env variables or configuration.
