Hi Bianca
Thanks for clarifying this.
You could use a label with a link to the policy or the content of the policy included (label content can be formatted as required) and prompting to tick the completion box to consent to the policy.
This activity can have completion tracking on 'Learners can manually mark the activity as complete'
The other topics or activities can then have Restrict access set to available when the Policy activity has been completed.
Regards
