How to auto renew SSL for stand-alone mode?

[04116]

Hi, I already got the certificate via acme.sh
I am thinking about two ways:
1- write app/shell to modify apisix.yaml
2- modify nginx_config in config.yaml

Not yet actually did above solutions because 1-complex, 2-may be not work.
Any suggest?

Thank,
