Is there any way to import a BIP39 seed to bitcoin core?

You can't directly import BIP39 seeds because support for that hasn't been implemented, however you can import it into another wallet, have it generate a bunch of addresses, export the private keys of them all and then import them into Bitcoin Core.

For example, using Electrum, after you import your BIP39 seed you'd go to Wallet > Private Keys > Export and then type a name for the file which it will dump all the private keys in, one key per line.

Then you make a new Bitcoin Core wallet and in its console you would type "importprivkey <private-key>" for each private key.

It's valid solution, but complicated and risky (since you expose the private key).

It's easier and safer if you use Electrum to send whole Bitcoin to address generated by Bitcoin Core with 1 sat/vbyte fee. Obviously there are fee concern if you have many input (especially if each input hold small amount of Bitcoin) & privacy concern if you have many address for many usage.
