Can FiveM takedown my server for using GTA 5 DLC (Casino) CARS

Actually, I’m planning to add some PDM cars which are not pre-added in the FiveM I’m taking them from the Official DLC of the GTA 5, So If I do so will it break any FiveM policy I’m kind of confuse should I put them on sale in my PDM or not. Kindly help, please.

No, of course not - you are not explicitly disallowed to use R*-made assets on your server for any intent or purpose.
