@Amir Sadvakassov Currently we support fetching backup items list and backup jobs without installing MARS agent, directly from the vault. But for recovery you would need to continue using MARS agent commands.
Adding commands for fetching backup item/jobs:
1) Get-AzRecoveryServicesBackupItem -BackupManagementType MAB -VaultId $vault.ID -WorkloadType FileFolder
2) Get-AzRecoveryServicesBackupJob -BackupManagementType MAB -VaultId $vault.ID
