use letsencrypt certificates for Sonic wall firewall

can we use letsencrypt certificates for Sonic wall firewall.
issue: DPI SSl is enabled for users & firewall self signed SSL certificate is pushed to clients by GPO. but when applying the filtering rules for mobile users (smart phones, Iphones, IPads & other computers that are not part of internal domain) they get SSL not trusted error. cannot perform https filtering with this error. so is there any way to use a publicly trusted certificate for my sonic wall local IP or any workaround to filter https for those clients.
Sonic OS 6.5 later  

thank you.

Using a proxy, problem is those would allow SSL traffic also to pass through transparantly.
You probably would need to filter on the enddevices themselves to do it correctly.

But i have seen some implementation where banking applications complained  about invalid certificates or where google whould indicate unreliable links because the "firewall" applications provided the same kind of service.
stripping SSL and examining content. SSL is designed to prevent examining & modifying data.
Individual proxy config cannot do for external users every time. windows computers can work with auto proxy config. but mobile devices still not support that.
