I know you can enable Windows 10 Developer mode interactively by going to Settings | For developers, selecting \'Developer mode\' and then rebooting.
Is there a way
Turns out Nickolaj Andersen has written an article which includes just such a PowerShell script..

Here are the relevant lines extracted from his post:
# Create AppModelUnlock if it doesn't exist, required for enabling Developer Mode
$RegistryKeyPath = "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\AppModelUnlock"
if (-not(Test-Path -Path $RegistryKeyPath)) {
New-Item -Path $RegistryKeyPath -ItemType Directory -Force
}
# Add registry value to enable Developer Mode
New-ItemProperty -Path $RegistryKeyPath -Name AllowDevelopmentWithoutDevLicense -PropertyType DWORD -Value 1
