How can I use aliases in bash scripts without changing the scripts?

I know writing

source ~/.bashrc
shopt -s expand_aliases

in a bash script allows to use aliases defined in .bashrc file.

However, I have so many bash scripts, and I cannot change all those scripts.

Is there a way to let my aliases used in all my scripts, with setting env or something?

Put the code that enables aliases and sources .bashrc to another file, assign its path to BASH_ENV, and export BASH_ENV.

$ cat .bashrc
alias dt=date

$ cat my_env.sh
shopt -s expand_aliases
source ~/.bashrc

$ cat my_script
#!/bin/bash
dt

$ export BASH_ENV=my_env.sh
$ ./my_script
