How to disable the log prefix of bpf_trace_printk

When I use bpf_trace_printk to output logs, it always has the prefix "bpf_trace_printk", which is useless. Does anyone know how to disable it?
```
bpf_trace_printk:#########################
bpf_trace_printk:#########################
bpf_trace_printk:From service to client
bpf_trace_printk: ep_to_client_key(src) is:
```

The issue does not name any files, tests, or entry points beyond bpf_trace_printk. Start by investigating how bpf_trace_printk formats its output and whether the bpf_trace_printk prefix can be disabled; done would be a documented or implemented way to produce the requested output without that prefix.
