does anyone have an example of how would I load an .env variables into ktor before starting local env or running tests?

You can't add env variables to a jvm process once it's started, so your only option is to read that file from gradle and append env variables to task's jvm fork

[Todd]

This is what I do for when I run gradlew run

val run by tasks.getting(JavaExec::class) {
    file(".env").readLines().forEach {
        if (it.isNotEmpty() && !it.startsWith("#")) {
            val equalsPos = it.indexOf("=")
            val key = it.substring(0, equalsPos)
            val value = it.substring(equalsPos + 1)

            if (System.getenv(key) == null) {
                environment[key] = value
            }
        }
    }
}

Doesn’t handle all of the cases, but can probably do what you need

I use Dotenv for this -> https://github.com/cdimascio/dotenv-java
There is a doten-kotlin plugin by the same author, but it doesn’t add much imo

You can use the HOCON configuration that loads values from environment variables https://ktor.io/docs/configurations.html#environment-variables.
