can az cli command automatically retry in case of http error 429 - azure

Question

I have observed that az command prints http headers only if --debug flag is passed to it.
E.g.
az storage account list --debug
and headers are printed to stderr and stdout contains nothing.
In case of HTTP 429, too many errors errors, guidance is to retry after interval mentioned in Retry-After response header.
Is there any mechanism that can make az cli automatically retry the API in case of HTTP 429 error?
Edit -- Retries built into az command
urllib3.util.retry : Incremented Retry for (url='/subscriptions/REMOVED/providers/Microsoft.Storage/storageAccounts?api-version=2019-06-01'): Retry(total=3, connect=4, read=4, redirect=None, status=None)

Base on the responses received so far, answer is "No" and that caller must run az command with --debug option and parse stderr. Here is sample Groovy code.
def pat = /'Retry-After': '(\d+)'/
stderr.split("\n").each { line ->
def m = line =~ pat
if (m.size() > 0 && m.hasGroup()) {
retryAfterDuration = Integer.parseInt(m[0][1])
println("Found Retry-After header, value = ${retryAfterDuration}")
}
}
Here is sample response.
