Assign static IP to docker container in macvlan network

Hello guys, I’m trying to assign static IP addresses to my docker containers in my macvlan network because every time I restart the docker instance (e.g for an update) o I restart the containers in that network all the IPs get messed up and this is a problem since my AdGuard Home DNS service changes its IP. I use to create the containers through stack in Portainer. Everything is running on a Synology NAS.

This is the conf that I tried to use, reading here and there it was the most suggested solution, but with this one docker-compose tries to create another network called “adguard_macvlan” but that it’s something that I don’t want since I already have my macvlan network.

version: '3.8'
services:
  adguard:
    container_name: AdGuard
    networks:
      macvlan:
        ipv4_address: 10.10.10.251
    image: adguard/adguardhome
    volumes:
      - /volume1/docker/adguard/data:/opt/adguardhome/work
      - /volume1/docker/adguard/config:/opt/adguardhome/conf
    ports:
      - "53:53/tcp"
      - "53:53/udp"
      - "80:80/tcp"
server
      - "3000:3000/tcp"
    cap_add:
      - NET_ADMIN
    restart: unless-stopped

networks:
 macvlan:
  driver: macvlan
  driver_opts: eth0
    ipam:
     config: 
       - subnet: 10.10.10.0/24
         gateway: 10.10.10.1 

Thanks for your help.
