I am able to grant accessibility permission using adb. Please see the command below
adb shell settings put secure enabled_accessibility_services <package_name><package-name>.AccessibilityServiceName
Is there a way to grant VPN permission via adb too?
TLDR: You cannot use that command, and you cannot use another permission based command either.
The only solution I could think of is it to use adb to press the OK button on the Connection request alert dialog generated by the OS:
adb shell uiautomator dump /sdcard/Download/view.xml
adb pull /sdcard/Download/view.xml
Observe the file, it contains the alert dialog. Specifically, OK is:
<node index="2" text="OK" resource-id="android:id/button1" class="android.widget.Button" package="com.android.vpndialogs" content-desc="" checkable="false" checked="false" clickable="true" enabled="true" focusable="true" focused="false" scrollable="false" long-clickable="false" password="false" selected="false" bounds="[564,2040][1008,2148]" /></node>
coords=$(perl -ne 'printf "%d %d\n", ($1+$3)/2, ($2+$4)/2 if /text="OK"[^>]*bounds="\[(\d+),(\d+)\]\[(\d+),(\d+)\]"/' view.xml)
adb shell input tap $coords
Mostly inspired from Apricot's answer.
You might have tried: adb shell pm grant com.example.package_name android.permission.CONTROL_VPN, but that won't work.

You have to request the permission using prepare(context).
settings command is doing?It's not for permissions.
enabled_accessibility_services is used to change the Settings (in the Settings app) to enable a specific accessible service declared in an application. In this case, this accessibility service still needs the "android.permission.BIND_ACCESSIBILITY_SERVICE" permission. It cannot add it through ADB.
There is no equivalent for VPN permissions within this, this command doesn't give permissions to applications, it configures the OS settings.
