@Vinod Sur, Thanks for posting in Q&A. For the setting "Require additional authentication at startup'". Based on my researching, it will set
"Configure TPM startup"
"Configure TPM startup PIN"
"Configure TPM startup key"
"Configure TPM startup key and PIN"

Note: Non-Microsoft link, just for the reference.
For such setting, in Intune, we can configure a similar setting named "Startup authentication required" under Endpoint security disk encryption policy or endpoint protection policy:

Hope the above information can help.
