@JanNuaman-2253 Thanks for posting in our Q&A.
There are two ways to create your company terms and conditions. One is via intune, the other is via Azure AD terms of use feature.

I have tried do deploy it via intune in my lab, it will display automatically when I login in the company portal app.
In Intune, terms are shown during device enrollment as well as inside the Company Portal for an already enrolled device. In Azure AD, you can choose to have your terms shown in other places and for more scenarios. For more details, please refer to the following article:

By the way, what did you mean "How about the time of enrollment using intune company portal"?
