I'm using Moto XT-1095. The default parameters are:

ATQA: 0x0004
Historical Bytes: N/A

To be compatible with an existing reader, I have to set the parameters as:

ATQA: 0x0008
Historical Bytes: 0x4858

Currently, I do this by modifying nfa_dm_discover.c to set NFC_PMID_LA_BIT_FRAME_SDD to 0x08 and to add NCI_PARAM_ID_LA_HIST_BY field.

Is it possible to change these parameters without modifying the ROM or rooting?

No, the Android NFC/HCE API does not allow you to set these parameters. Thus, the only options are to create your customized ROM that provides a means to set these parameters or to modify libnfc-brcm.conf on a rooted device.
