This would drop support for all Puppet version > 6 because the Type "Deferred" isn't known by Puppet 4/5.

I've implemented this without knowing someone else already did it. I think I found solution which supports Puppet 4/5/6.

Integer[1,65535] $listen_port,
Enum['present','absent'] $ensure = 'present',
Optional[Array[Struct[
{
'PublicKey' => String,
'PublicKey' => Variant[String,Deferred],
'AllowedIPs' => Optional[String],
'Endpoint' => Optional[String],
'PersistentKeepalive' => Optional[Integer],
}
]]] $peers = [],
Boolean $saveconfig = true,
Stdlib::Absolutepath $config_dir = '/etc/wireguard',
]]] $peers = [],
Boolean $saveconfig = true,
Stdlib::Absolutepath $config_dir = '/etc/wireguard',
) {

$interface_template = @(EOF)
# This file is managed by puppet
