Hi Godwin,
Thanks for using Syncfusion Products.
We have analysed the your requirement for any sample level workaround to avoid Adornment intersection. We are unable to achieve as like AdjustAcrossPoints, since if we do any changes related with position in sample level it will affect all the adornments(not only the overlapping adornments).
We would like to inform you that this feature was available from 10.2 main release version, so you can upgrade to any versions from 10.2 for using this feature.
Please let us know if you have any queries,
Thanks,
Muneesh Kumar G.
