Is it possible to override the sampling rate, not decision, when you create a span without using the SDK part of opentelemetry-python?

When we create the tracer provider we create a ParentBasedTraceIdRatio that we use as the sampler which samples a globally defined rate of traces. In some high priority or low traffic but fragile endpoints/consumers we would like to sample 50% - 100% of the traffic instead of the default 0.1% - 1%. I generally don't want to override the sampling decision, I just want to control the sampling rate.

Right now the SDK part of the opentelemetry-python is safely tucked away in a single file in our application and the rest of the code always uses the API abstraction layers. When I call trace.get_tracer( I will get a tracer that have the applications default sampler, is there anyway to override the sampling rate for the new tracer without having to use the SDK files? I could always do

consumer_tracer: opentelemetry.sdk.trace.Tracer = get_tracer(options.app_name, options.app_version)
consumer_tracer.sampler = ParentBasedTraceIdRatio(0.5)

but then the application might crash if we use a DefaultTracerProvider tracer provider and is fragile in other ways.
