Is this an EASA country?
IACO doesn't cover those sort of procedures its sets the minimum standards, there is nothing stopping a country being more restrictive. So its not a case of ICAO allowing it more a case of nothing stopping them. So local CAA can stipulate what they like for their national license holders.
Again if its a validated EASA license again the local CAA can put whatever restrictions on it likes.
To be honest its sounds like you are not working for an EASA AoC holder. Local rules will carry the day and they can do what they want.
