Fetch user from different shard (without being in the same guild)

I'm working on a notification function to send DM user . But I read some information online that using .broadcastEval() may result in multiple messages will be send if that user is currently in cache of multiple shards. So in my current implementation, I'm using cron job running on shard manager to check when to send user a DM and picking random shard to send it like this: Code in shard manager

            // Pick random shard to dm user to prevent dulicate message
            const totalShard = manager.totalShards;
            const rngShard = getRandomInt(totalShard);
            manager.broadcast({ name: 'dmUser', id: id, msg: msg, shard: rngShard });

            // Pick random shard to dm user to prevent dulicate message
            const totalShard = manager.totalShards;
            const rngShard = getRandomInt(totalShard);
            manager.broadcast({ name: 'dmUser', id: id, msg: msg, shard: rngShard });

Code in client

process.on('message', async function(m) {
        //...
    if (m.name === 'dmUser') {
        // Check if this shard is the one assigned to dm user
        if (client.shard.ids[0] === Number(m.shard)) {
            const user = await client.users.fetch(m.id);
            if (!m.msg || m.msg === '') {
                return;
            }
            await user.send(m.msg);
        }
    }
}

process.on('message', async function(m) {
        //...
    if (m.name === 'dmUser') {
        // Check if this shard is the one assigned to dm user
        if (client.shard.ids[0] === Number(m.shard)) {
            const user = await client.users.fetch(m.id);
            if (!m.msg || m.msg === '') {
                return;
            }
            await user.send(m.msg);
        }
    }
}

but my bot is still in development and don't have enough user to spawn multiple shards yet, so I have no way to test if my shard can fetch and DM that user without being in the same guild as them

thanks for your answer, I also want to know that if I can DM user is not in the same guild with the shard (something like the guild that user currently in belong to shard 1 but I want to use shard 4 to DM that user) fixed my question to clarify my intent

Yeah you dont need to DM a user from a specific shard In fact, all received DMs go to shard 0 anyway I think
