Q: if (name of operating system does not contain "Win") then "N/A" else ((if not exists key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Client" of native registry then "TLS 1.0: Key Not Found" else if ((value "Enabled" of key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Client" of native registry) = "1" AND (value "DisabledByDefault" of key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Client" of native registry) = "0") then "TLS 1.0: Enabled" else "TLS 1.0: Disabled") as string) & " || " & ((if not exists key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Client" of native registry then "TLS 1.2: Key Not Found" else if ((value "Enabled" of key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Client" of native registry) = "1" AND (value "DisabledByDefault" of key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Client" of native registry) = "0") then "TLS 1.1: Enabled" else "TLS 1.1: Disabled") as string) & " || " & ((if not exists key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client" of native registry then "TLS 1.2: Key Not Found" else if ((value "Enabled" of key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client" of native registry) = "1" AND (value "DisabledByDefault" of key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client" of native registry) = "0") then "TLS 1.3: Enabled" else "TLS 1.2: Disabled") as string)
A: TLS 1.0: Disabled || TLS 1.1: Disabled || TLS 1.2: Key Not Found

After adding it as a Reteried property in BigFix Console, you can use it straight from the console, WebUI, or Webreport.
