Change Default SAML Certificate Validity Years

Does anyone know if there is a way to change the default validity years of a SAML certificate?

From what I have noticed the SAML certificate that’s auto generated each time a SAML app is created is valid for 10 years. Okta does allow the creation of new certificates with the timeframe being as low as 2 years via the API, but it also requires two additional API calls(one to create and one to activate) each time a SAML application is generated.
