CAN Task Scheduling

If you want to send a CAN message from when the VCU wakes up until it goes to sleep, we can follow the test model (Fig. 1).
How can we send messages at specific times. For example, the VCU should turn off messages while charging an EV. Is this a good practice:
Create a rate-dependent trigger with the option to turn the trigger off [CAN_On !=2] (Figure 2,3)
Place the message with the inherent task in a triggered subsystem (Fig. 4)
