Answer is - no way. But you can use toncli to do it for you.
For example - the basic example of wallet use wallet.fif to generate boc files, then they will be pushed to network with lite-client.
In wallet example you can find fift/usage.fif file. This is wallet.fif but we added one feature there.
You can see that last line is saveboc. It's needed for saving boc file in build/boc location (or /tmp if you run command not in project root) and then our CLI tool can catch it and send to network.
E.g.:
toncli fift sendboc ./fift/usage.fif build/contract EQB36_EfYjFYMV8p_cxSYX61bA0FZ4B65ZNN6L8INY-5gL6w 0 0 0.01
Usage.fif takes some arguments to generate boc file, those are: file_base, wallet, subwallet_id, seqno, ammount.
Seqno can be founded by get method seqno:
(base) tvorogme in /tmp/wallet λ toncli get seqno

Seqno is 0 in this example.
If you run sendboc command in wallet project, and pass all arguments right you will see that boc file will be sent with lite-client.
E.g.:
(base) tvorogme in /tmp/wallet λ toncli fift sendboc ./fift/usage.fif build/contract EQB36_EfYjFYMV8p_cxSYX61bA0FZ4B65ZNN6L8INY-5gL6w 0 0 0.01
