Netplan 桥接主机获取静态 IP 地址而不是桥接器

我正在尝试为 KVM 客户端和主机连接配置桥接器。桥接器从未正确配置，物理 NIC 总是最终获得静态 IP 地址，而桥接器被分配动态 IP 地址。路由器中保留了静态 IP，这可能是导致这种情况的原因，但我不想删除 DHCP 保留。我做错了什么吗？

我的 Netplan 配置如下：

network:
    version: 2
    renderer: NetworkManager
    ethernets:
        enp2s0:
            dhcp4: no
            dhcp6: no
    bridges:
        br0:
            dhcp4: no
            dhcp6: no
            interfaces: [enp2s0]
            gateway4: 192.168.0.1
            addresses: [192.168.0.100/24]
            macaddress: 40:b0:34:30:c5:bf # Same as the physical NIC
            nameservers:
                addresses: [8.8.8.8, 8.8.4.4]
            parameters:
                stp: false
                forward-delay: 0

netplan --debug apply输出：https://pastebin.com/9yfMfWj0

ip route输出：

编辑1：

我尝试过使用 networkd 并禁用 NetworkManager，但还是遇到了同样的问题。我注意到桥接器被分配了列出的静态 IP 和辅助 IP，但静态 IP 也分配给了物理卡。

ip addr输出：
