NativeTransferBuilder might be extended like this:

export class NativeTransferBuilderWithSrId extends NativeTransferBuilder {
  private _sr_id: any;

  constructor() {
    super();
    this._sr_id = null;
  }

  /**
   * Sets the transfer ID.
   */
  public srId(value: number): any {
    let arr = new Array<number>(32).fill(0);
    arr[0] = value;
    this._sr_id = CLValue.newCLByteArray(Uint8Array.from(arr));
    return this;
  }

  /**
   * Builds and returns the Native Transfer transaction.
   */
  public build(): any {
    const transactionV1 = super.build().getTransactionV1();;
    if (!transactionV1) {
      throw new Error("TransactionV1 is not correct. Check the parameters.");
    }
    transactionV1.payload.fields.args.insert("sr_id", this._sr_id);
    const _transactionV1 = TransactionV1.makeTransactionV1(
      transactionV1.payload,
    );
    return Transaction.fromTransactionV1(_transactionV1);
  }

  public buildFor1_5(): any {
    throw new Error("Use build() instead");
  }
}

then:

const transaction = new NativeTransferBuilderWithSrId()
        .srId(15)
        .from(privateKey.publicKey)
        .target(PublicKey.fromHex('0202f5a92ab6da536e7b1a351406f3744224bec85d7acbab1497b65de48a1a707b64'))
        .amount('4200000000')
        .chainName('casper-test')
        .build();
