I am trying to create an RF remote that has 6 buttons but the RF encoder only has 4 inputs. Is this possible and preferably I would not like to use a separate chip.

This is what I am using:

The IC has four inputs, you can activate multiple inputs at once, for 15 unique switch combinations.

You could use six diodes to decode 6 switches into 4 inputs.

It has 4 inputs, which means you can input \$2^4\$ combinations of these inputs. To translate button presses to binary numbers, a priority encoder is needed, such as this one.
