When changing a password via PowerShell, is there a way to bypass the prompt that asks for the existing password?

Below I have some code that will ask the user for their admin credentials and if they’re within that domain, the script proceeds and then resets the password of a user of their choosing. It works…but, the one I’m writing this for wants to be able to bypass the prompt that comes up by default asking for the user’s existing password before it gets reset. He doesn’t know everyone’s password and would rather not dig for it. I cannot find ANYTHING on how to do this online. Does anyone have suggestions? I have my code below and the lower half is just the addition of a text box so you can ignore it. Thanks!

# Function to generate a random password
function Generate-RandomPassword {
    param (
        [int]$Length = 12
    )
    
    $charPool = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*()-_=+[]{}|;:',.<>/?"
    $password = ""
    
    for ($i = 0; $i -lt $Length; $i++) {
        $password += $charPool[(Get-Random -Minimum 0 -Maximum $charPool.Length)]
    }
    
    return $password
}

# Verify if the provided admin is in the domain

        })
