Changing Naming Rule of Core Doctype

What is the ideal way to change naming rule of a core doctype. I want to change naming rule of a core doctype from naming series to auto increment.

Not a fan of doing customize form in every system since iam working on local environment and i want to reflect the changes in dev environment and prod environment.

@Ashique You can use Document Naming Settings

can we change the rule there ? when i checked it seems like we can configure multiple naming series there. i want to change the rule. to auto increment or random or expression etc.
please guide me if i’m wrong

@Ashique Yes, we can change

can we get all these rules in the document naming settings. i want Autoincrement rule actually. can you please guide me

@Ashique

Don’t know exactly, but you can use expression

Okay thank you.
let me work on this and will let you know if there is an update
