I was researching your issue and was only able to find a way to do this using the Azure Portal. Additionally, I tried using PowerShell and CLI commands but wasn't able to download a certificate in .cer format.

You can find a complete list of PowerShell and CLI commands for the Azure Key Vault below:

PowerShell - Azure Key Vault

CLI - Azure Key Vault

I'll reach out to my team to see if there are any other options when it comes to downloading a certificate in .cer format.

$secret = Get-AzKeyVaultSecret -VaultName $vaultName -Name $certificateName
$secretByte = [Convert]::FromBase64String($secret.SecretValueText)
$x509Cert = new-object System.Security.Cryptography.X509Certificates.X509Certificate2
$x509Cert.Import($secretByte, "", "Exportable,PersistKeySet")
$cer = Export-Certificate -Cert $x509Cert -FilePath $env:temp\certificate.cer
Write-Output $cer

this worked for me
