It’s not the best idea to use RF filtering to limit audio bandwidth.

I don’t think the AM transmit bandwidth relies on the filter to set its limits.
Even with the 13KHz filter, bandwidth is limited by the DSP. The option to
use the 13KHz filter was, as I recall, a change made by Elecraft quite some
time ago. While there are many opinions, there is no
Yes true, however I don't suggest using the 13 kHz filter for AM
transmit in view of transmit bandwidth considerations. The 6 kHz
filter is more appropriate and thus does limit the transmit bandwidth to
the required limits of the regulations. 97.101(a)

Or the 13 kHz filter. Both the 6 and 13 kHz filters can be used for AM.

Sure, works great. As configured for SSB switching to AM mode runs
about 125 watts of carrier from the KPA500. No different than
operating SSB, just switch the K3S to AM. Must have the 6 kHz filter
installed.

Anyone have any experiences or suggestions for using the K3s, KPA500 and KAT500
