NFS VAAI plugin for VMware 

VMware vSphere Storage APIs – Array Integration (VAAI) is a set of APIs that offload specific storage-related operations from the ESXi host to the storage array, thereby enhancing performance and efficiency. By letting the storage array handle intensive tasks (like cloning or snapshot creation), you reduce resource usage on the ESXi host and improve overall storage operations.

The plugin is available for version up32 onward.
 

1.1. Download the plugin

Download the plugin attached in the article.

1.2. Install the plugin for VAAI

Acceptance Level and No Signature Check

If you don't need VMware certification when you install your VIB on an ESXi host, you can set the host's acceptance level to Community Supported. To check the acceptance level, run the command below:
 

esxcli software acceptance get
PartnerSupported

In this case it is supported by a partner. To lower the ESXi host's acceptance level to Community Supported, run the command below:

esxcli software acceptance set --level=CommunitySupported
CommunitySupported

Changing the ESXi host’s acceptance level to Community Supported should be done only for testing.
Never do so in a production environment, because it reduces security and supportability of your software by VMware and partner support organizations
 

Now you can install the vib plugin without a valid signature using option --no-sig-check. 

esxcli software vib install -v /vmfs/volumes/datastore1/dss-ESX-JovianDSS_NFS_Plugin.vib --no-sig-check
