@HM, Thanks for posting in Q&A.
Based on my research, Not all GPO settings have a direct equivalent in Intune. For settings that are unsupported or missing in Intune, you might need to use OMA-URI settings, so, without knowing exactly which settings you are referring to here, no concrete help can be provided except to go search the Settings Catalog. @Joost Gelijsteen posted a couple of great links.
And finally, if you want to still some analysis and conversion, there is a tool called Group Policy Analytics that will help you with this: https://learn.microsoft.com/en-us/mem/intune/configuration/group-policy-analytics
Hope above information can be helpful.
