As other posters have noted, you can change the entire device to packet mode to gain mpls support.
You can, however, remain in flow mode and switch individual interfaces to packet mode, allowing configurations with both packet mode-only features (e.g., MPLS) and flow mode-only features (IPSec, stateful firewalling). You do this by leaving the box in flow mode overall. Interfaces are placed in packet-mode using filters with "then packet-mode" as the terminating action.
You can find a good example in NCE-140, "
Configuring Branch SRX Series for MPLS over GRE with IPsec Segmentation."

Subject: MPLS not supported on vSRX with flow-based mode, right ?
I have a topology with a vSRX as P router. MPLS is not supported on it with flow-based mode, right ?
thanks !!
