How to Disable certificate check with OIDC Auth

Hi team, for testing purpose,
Is it possible to disable certificate check when configuring OIDC authentication method.

through vault write auth/oidc/config oidc_discovery_url=“xxx” oidc_client_id=“xxx” oidc_client_secret=“xxx”

I got the following message :

error checking oidc discovery URL: error creating provider with given values: Get https://xxxxx/.well-known/openid-configuration: x509: cannot validate certificate for xxxx

It not for production but for testing purpose.
Thanks a lot.
