Disabling markdown at a section level is now supported in Cards. You can set `markdown` to false.

Details [here](https://learn.microsoft.com/en-us/microsoftteams/platform/task-modules-and-cards/cards/cards-reference#office-365-connector-card)

**Example**

```
{
"@type": "MessageCard",
"@context": "https://schema.org/extensions",
"summary": "Office 365 Notification",
"title": "Office 365 Service Degradations",
"sections": [
{
"markdown": false,
"facts": [
{
"name": "Service Incident:",
"value": "ID"
},
{

{
"name": "Service:",
"value": "SERVICENAME"
},
