请问如何更改默认生成的yaml生成的缩进

请问如何更改默认生成的yaml生成的缩进，默认生成的是四个空格，看着太难受了，是否可以增加一个参数让使用者在生成的时候自主选择缩进？
Hello， it is there anyway to change the indentation of the default generated yaml. The default generated yaml is four spaces, which looks too uncomfortable. Is it possible to add a parameter to allow users to choose the indentation when generating?
