Hi everyone! I have a flow which I want to deploy multiple times with different parameters. The only problem is that I want some parameters to be not modifiable when a user does a custom run. How can I achieve this?

not sure it's possible
you could retreive their parameters from a database instead
hard to give more advise without knowledge of the usecase & minimal code of example

it could be also a python dictionary, the only problem is 
how to identify the deployment which triggered the flow?
If I know if I could implement the logic and even avoid to present these parameters in the ui

from prefect import flow
from prefect.context import get_run_context


@flow
def main():
    ctx = get_run_context()
    print(ctx.flow_run.deployment_id)

it should do the tricks

get_run_logger().info(get_client().read_deployment(FlowRunContext.get().flow_run.deployment_id).name)
I found it! Thanks!

else pernaps you can store some args as infra args ?
(I never used infra args so idk)

they are not sensitive, they can be also in the code. Anyway, there are also variables in Prefect which can be used to store parameters that every deployment can read
